Seek emergency care immediately if the pain is sudden or crushing, radiates to the chest/jaw/back/neck, or is accompanied by shortness of breath, cold sweat, nausea, lightheadedness, fainting, or a rapid/irregular heartbeat. Otherwise, see a doctor if it lasts more than a few days, worsens or limits activity/sleep, follows an injury, involves swelling/redness/warmth, numbness/tingling/weakness, or if you have heart risk factors (heart disease, diabetes, high blood pressure). There are several factors to consider—see below for the full list of red flags, common causes, what tests to expect, and safe self-care steps that could affect your next move.

Yes—being open with your OBGYN about dildo use helps them check for irritation or injury, guide STI screening and infection prevention, recommend the right lubricants and cleaning methods, and tailor advice for comfort, anatomy, and pelvic floor needs. If you’ve had persistent pain, bleeding, unusual discharge, or other concerning symptoms, seek care; there are several factors to consider—see below for what details to share, how to bring it up, cleaning and sharing safety, and urgent red flags.

For quick, safe relief of testicle pain, apply a wrapped ice pack for 10–15 minutes at a time, wear snug support (jockstrap/briefs), rest, and consider OTC pain relievers; a warm sitz bath can help if muscles are tight. There are several factors to consider, and urgent symptoms like sudden severe pain, swelling/redness, nausea/vomiting, fever, blood in urine/semen, a high-riding testicle, or pain lasting hours need immediate care (torsion can be time‑critical). See below for full details on causes, prevention, when to see a doctor, and a free symptom check to guide next steps.

Early effects can be subtle—nausea, vomiting, loss of appetite, sweating/pallor, and mild abdominal discomfort—then 24–96 hours later may progress to right‑upper‑abdominal pain, markedly abnormal liver tests, jaundice, easy bruising/bleeding, low blood sugar, confusion/encephalopathy, and potentially acute liver failure. Other serious complications include acute kidney injury (reduced urine), pancreatitis, metabolic acidosis, low blood pressure, respiratory distress, and even multi‑organ failure; there are time‑sensitive steps (e.g., antidote timing with N‑acetylcysteine, lab monitoring, ER evaluation) and risk factors that affect outcomes, so see the complete details below and seek urgent medical care if an overdose is possible.

You generally can’t make a stye disappear overnight, but you can quickly reduce pain and swelling with frequent warm compresses (10–15 minutes, 3–5 times/day), gentle lid hygiene, stopping makeup/contacts, and, when appropriate, an antibiotic ointment or prescription azithromycin 1% eye drops—never squeeze it. Most clear in 7–10 days; seek care sooner for worsening redness/swelling, vision changes, or fever. There are several factors and options (including when to use oral antibiotics or drainage) that could change your next steps—see the complete guidance below.

CDC recommends isolating for at least 5 days after symptom onset or a positive test (Day 0 is the day symptoms start/test), ending after day 5 only if you’ve been fever-free for 24 hours and symptoms are improving; keep masking around others through day 10 (asymptomatic isolate 5 days; severe illness or weakened immunity may need 10+ days). There are several factors to consider—who needs to isolate (including some close contacts), optional test-based clearance, avoiding high‑risk settings until day 11, and what to do if symptoms return—see below for important details that could change your next steps.

Most common COVID symptoms in kids are fever and cough, plus runny or congested nose, sore throat, fatigue, and headache; many cases are mild, but some children also have gastrointestinal symptoms (nausea, vomiting, diarrhea), and loss of taste or smell is less common. There are several factors to consider—see below for age-specific patterns, red flags (breathing trouble, dehydration, persistent high fever, MIS-C), and clear guidance on when to test, isolate, manage at home, or seek urgent care.

Most infections with the latest Omicron-derived subvariants look like a bad cold: runny or congested nose, sore throat, headache, mild cough, fatigue, sneezing, and body aches; fever and loss of taste/smell are less common but can still occur. There are several factors to consider—including less common symptoms (like GI upset or chest tightness), who’s at higher risk, when to seek urgent care, and what to do next (testing and isolation); see the complete details and next-step guidance below.

Lower left abdominal pain in women can stem from the GI tract (diverticulitis, IBS/IBD, constipation, colitis or obstruction), gynecologic causes (ovarian cysts or torsion, ectopic pregnancy, endometriosis, PID, ovulation pain), urinary issues (UTI, kidney stones, pyelonephritis), or musculoskeletal/hernia and vascular problems. There are several factors to consider—and some are emergencies, especially sudden severe pain, fever, vomiting, abnormal vaginal bleeding, or symptoms in early pregnancy—so see the complete details below to recognize red flags and choose the right next steps.

Sudden left arm pain can arise from heart problems (heart attack or angina, rarely aortic dissection), but also from muscle/tendon strain or rotator cuff issues, pinched nerves in the neck, and less commonly lung/vascular conditions, reflux, or shingles. Get emergency care if it comes with chest pressure, shortness of breath, sweating, fainting, or pain spreading to the jaw or back; activity-linked, tender, or tingling pain may point to musculoskeletal or nerve causes. There are several factors to consider—see below for important details and next steps that could affect what you do next.

Low alkaline phosphatase can result from genetic hypophosphatasia; nutrient deficiencies (zinc, magnesium, protein); endocrine issues (hypothyroidism, poorly controlled diabetes); hematologic disorders (vitamin B12 deficiency, aplastic anemia); malabsorption (celiac/IBD); liver/metabolic disease (Wilson disease, severe fatty liver); severe illness or cachexia; medications/toxins (chemotherapy, corticosteroids, heavy metals); and even lab handling or assay errors. Mild reductions can be benign, but very low levels—especially with bone pain, fractures, jaundice, or persistent fatigue—warrant medical follow‑up; there are several factors to consider, and important testing and next steps are detailed below.

In women, pain under the right armpit can stem from muscle strain; swollen lymph nodes or skin infections (including abscesses or shingles); breast issues like mastitis or, less commonly, cancer; nerve problems; referred pain from the gallbladder or liver; or even a vein clot. There are several factors to consider—see below for specifics, urgent warning signs (severe chest pain or breathing trouble, fever with redness, arm swelling/discoloration, rapidly growing lumps with night sweats/weight loss), and next steps including self-care for mild strain versus seeing a clinician if symptoms persist beyond 1–2 weeks or worsen.

Most people have mild, short-lived reactions after a COVID-19 shot—sore arm, fatigue, headache, muscle/joint aches, chills, or low‑grade fever—starting within 12–24 hours and resolving in 1–3 days (often stronger after second or booster doses). Serious side effects are rare but include severe allergy, myocarditis/pericarditis, or rare clotting events; seek urgent care for chest pain, trouble breathing, hives/swelling, severe headache, leg swelling, or persistent/worsening symptoms. There are several factors to consider—see the complete guidance below for who tends to react more, how to manage symptoms, when to call a doctor or use a symptom checker, and how to report side effects.

Low alkaline phosphatase means your level is below the lab’s reference range and is most often tied to nutrition or absorption issues (low protein, zinc, magnesium, B12), hypothyroidism, chronic liver disease, or rarer conditions like hypophosphatasia or Wilson’s disease; most cases are mild and reversible. There are several factors to consider—see below for detailed causes, red-flag symptoms (bone pain or fractures, jaundice, neurologic changes), and clear next steps such as repeating the test, checking related labs, reviewing diet/medications, and when to see a clinician.

Fast relief typically comes from rest and supported positioning, cold for the first 24–48 hours then heat, over-the-counter pain relievers (ibuprofen/naproxen or acetaminophen), topical gels, gentle stretching or self‑massage, a TENS unit, and quick ergonomic adjustments. There are several factors and warning signs that could change your next steps—especially chest pain or shortness of breath, sudden severe pain, numbness/weakness, or fever/redness—so review the complete guidance below to know when to continue self-care versus seek urgent care.

Quick at-home relief includes warm compresses, gentle eyelid massage, frequent blinking with lubricating drops, brief cold packs, cutting back caffeine, managing stress, taking screen breaks, and getting more sleep; some women also find magnesium (200–400 mg/day, with your doctor’s okay) helpful. There are several factors to consider— including hydration and nutrition to prevent recurrences and red-flag symptoms (lasting >2 weeks, spreading to the face, pain/redness/discharge, or vision changes) that warrant medical care—see the complete guidance below.

The “razor threat” COVID variant isn’t an official WHO designation but a media nickname for spike mutations; early lab data suggests modest immune escape, with no real-world evidence it’s more severe in children. Parents shouldn’t panic—keep up vaccination/boosters, masking in crowded indoor spaces, good ventilation and hand hygiene, and test promptly while watching for red-flag symptoms, especially in kids with chronic conditions. There are several factors to consider that could change your next steps (when to test, isolate, or seek urgent care); see below for important details and tools.

Start treatment early—ideally within 5 days—with antivirals if you’re higher risk (older age, chronic conditions, or immunocompromise): Paxlovid is preferred, or molnupiravir if Paxlovid isn’t suitable; for symptom relief use acetaminophen/ibuprofen, cough lozenges or syrups, decongestants, fluids, and rest. There are several factors to consider—drug interactions (especially with Paxlovid), pregnancy, kidney/liver problems, and red‑flag symptoms—see the detailed guidance below. Confirm it’s COVID, contact your clinician promptly to review eligibility and dosing, and follow the isolation/masking and monitoring steps outlined below.

Watch for mild issues like upset stomach, headache, dizziness, or a light rash, but seek urgent care for hives, facial/lip/tongue swelling, trouble breathing, or any signs of liver injury/overdose such as persistent vomiting, severe upper-right belly pain, jaundice (yellow eyes/skin), dark urine, confusion, unusual sleepiness, or easy bruising/bleeding. If you suspect too much was taken, call Poison Control (1-800-222-1222) or go to the ER—there are several factors (weight-based dosing, hidden acetaminophen in combo cold/flu meds, liver disease, dehydration, drug interactions) that can raise risk; see the complete guidance below to understand what to do next.

Left arm pain is more likely from a nerve when it’s burning, shooting, electric, or “pins and needles,” follows a clear path from the neck/shoulder into the hand, and includes numbness or specific weakness—often aggravated by neck, wrist, or elbow positions. There are several factors to consider, including important look‑alikes (heart pain, muscle/joint issues) and red flags like sudden crushing chest pain or rapidly worsening weakness; see the complete guidance below for key signs, simple self-checks, and when to seek urgent care versus try conservative treatment.

Usually benign, but left eyelid twitching in women is more concerning if it lasts longer than two weeks, spreads to other facial muscles or forces the eye closed, follows head/eye injury, or occurs with neurological or systemic symptoms (facial weakness, vision or speech changes, numbness, fever, unexplained weight loss). These can point to blepharospasm/hemifacial spasm, thyroid eye disease, electrolyte issues, or neurological disorders (including stroke)—there are several factors to consider; see the complete details and recommended next steps below.

Lower left abdominal pain in women is serious when it’s sudden or severe, or accompanied by fever, persistent vomiting, fainting/shock, vaginal bleeding or possible pregnancy, inability to pass stool/gas with distension, or blood in stool/vomit—potential emergencies include ectopic pregnancy, ovarian torsion, diverticulitis complications, kidney stones/infection, bowel obstruction, or a ruptured ovarian cyst. Seek emergency care for these red flags; otherwise, call your clinician if symptoms last more than 48 hours or worsen. There are several factors to consider—see below for detailed causes, nuanced red flags, and the exact tests and next steps that could change your care.

There are several factors to consider—see below to understand more. Seek urgent care for trouble breathing, drooling or inability to swallow, a muffled “hot‑potato” voice, severe throat pain, severe neck stiffness with fever, very high fever, confusion, or dehydration; otherwise see a clinician within 48 hours if fever lasts >48 hours, swallowing is limited, you notice swollen tender neck nodes or white patches on the tonsils, a rash, ear/neck pain, hoarseness >2 weeks, or worsening symptoms. Mild cases often improve in 3–7 days with self-care, but infants/older adults, those with chronic illnesses or weakened immunity should be seen sooner, and testing can clarify if strep antibiotics are needed—details and next steps are outlined below.

The most important acetaminophen side effects that impact the liver are elevated liver enzymes (an early sign of injury), hepatic necrosis, and acute liver failure—often accompanied by jaundice, coagulopathy (easy bruising/bleeding), and hepatic encephalopathy (confusion). There are several factors to consider that can change your risk and next steps (dose limits, alcohol use, malnutrition, interacting medicines, early symptoms, and the role of N-acetylcysteine); see the complete guidance below.

Red-flag Tylenol side effects that may signal liver trouble include jaundice (yellow skin/eyes), dark urine, pale stools, right‑upper abdominal pain, persistent nausea/vomiting, extreme fatigue/weakness, loss of appetite, or confusion. If you notice any of these—especially jaundice, dark urine, or severe abdominal pain—stop Tylenol and seek urgent care; there are several important risk factors, safe‑dose limits, and next steps to consider—see details below.

There are several factors to consider. Even when not pregnant, post‑workout nipple pain is usually from friction/chafing, sweat/salt irritation, contact dermatitis, yeast/bacterial overgrowth, chest‑muscle strain, or normal hormone sensitivity—and it often improves with a well‑fitting moisture‑wicking sports bra, protective balm, and prompt drying. See below for step‑by‑step prevention and the red flags (new lump, discharge, spreading redness/fever, or skin changes) that determine when to seek medical care.

There are several factors to consider: even when not pregnant, nipple tenderness is usually benign and can result from cyclical hormone shifts (including perimenopause), stress-related cortisol changes and chest wall tension, friction from clothing or ill‑fitting bras, skin conditions or infections, medication effects, referred chest wall pain, and—less commonly—Paget’s disease or breast cancer. Try a supportive bra, stress reduction, warm/cold compresses or OTC pain relief, and track triggers; seek prompt care for persistent one‑sided pain, discharge (especially bloody/clear), nonhealing rash/ulceration, a lump, fever, or sudden severe pain—complete details and next steps are outlined below.

Most nipple pain during your cycle when you’re not pregnant is usually from normal hormonal swings (cyclical mastalgia) that increase breast sensitivity, but fibrocystic changes, skin irritation, friction, infection, or rarer issues can also contribute. Simple steps like a supportive bra, warm compresses, OTC pain relievers, and cutting back on caffeine/salt/alcohol often help, but seek care for one-sided or persistent pain, discharge, skin changes, a hard lump, or infection signs. There are several factors to consider and important next steps that may apply to you—see below for details.

Skin irritation is a leading cause—often from contact dermatitis (soaps/detergents, fabrics), eczema/psoriasis, chafing, or allergies—but hormones, infections (bacterial/yeast/herpes), injury, and rare conditions like Paget’s disease or inflammatory breast cancer can also contribute. Try gentle, fragrance-free products, a supportive bra, cool compresses, and short-term hydrocortisone for dermatitis, and seek care urgently for persistent/worsening pain, discharge (especially bloody), new lumps, spreading redness/fever, or nipple/skin changes. There are several factors to consider; key details and next steps that could affect your care are outlined below.

Rashes after COVID vaccines are uncommon (well under 1%) and usually mild—most stem from normal immune activation, such as immediate histamine-driven hives or a delayed T‑cell reaction like “COVID arm”—and resolve in days to weeks with simple care. It’s serious if there are signs of anaphylaxis within minutes (trouble breathing, facial/lip swelling), rapid spread with fever, blisters/peeling or mouth/eye/genital sores, or if it lasts >2–3 weeks—seek urgent care in these cases. There are several factors to consider, including timing and appearance; see the complete guidance below for key details that can affect your next steps and whether home care or a clinician visit is best.
