The Less Familiar Symptoms of the Newer COVID Variants

Newer COVID variants often show up with symptoms many people do not associate with the virus, including severe "razor blade" sore throat or hoarseness, nausea, diarrhea and stomach pain, pink eye, night sweats, dizziness, and brain fog, while classic signs like loss of taste and smell have become far less common. Fatigue, headache, and low appetite may be the only clues, which means a case can easily be mistaken for allergies, a stomach bug, or a routine cold. Symptom patterns also differ depending on vaccination history, prior infections, age, and underlying conditions, so two people with the same variant can feel very different. There are several important factors and warning signs to consider, including when testing timing matters most and which symptoms signal the need for urgent care, so review the complete answer below before deciding what to do next.

If you are unsure whether what you are feeling is COVID, allergies, or something else entirely, guessing wastes time you could spend getting better, and testing too early or too late can give you a misleading result. Take a free, instant, online symptom check to see how your specific symptoms line up, understand what may be driving them, and get clear guidance on your next steps.

The Less Familiar Symptoms of the Newer COVID Variants

As COVID-19 continues to evolve, newer variants can bring along unexpected or “weird” symptoms that many of us haven’t seen before. You might be wondering, what are the weird symptoms of the new covid variant? While classic signs—fever, cough, sore throat—remain common, here’s a closer look at less familiar clues your body might give you.

Why Symptoms Change with New Variants

Viruses mutate over time. Each new COVID variant can affect different parts of the body, trigger varied immune responses, or change the way it’s transmitted. Public health experts and clinicians track these shifts via testing data, patient reports, and studies published in credible journals like The Lancet, JAMA, and by organizations such as the CDC and WHO.

Unusual Respiratory and Throat Changes

Beyond the typical cough or scratchy throat, some newer strains have been linked to:

  • Throat tingling or burning
    A sharp, localized sensation when swallowing, distinct from a general sore throat.

  • Hoarseness or voice changes
    Persistent raspiness even without a heavy cough, possibly due to mild inflammation of the vocal cords.

  • Airway tightness or mild wheezing
    Not quite asthma, but a feeling of restricted airflow.

Strange Sensations in the Head and Ears

Neurological and ear-related symptoms can pop up unexpectedly:

  • Tinnitus or ringing in the ears
    A persistent buzz, click, or high-pitched tone that wasn’t there before.

  • Dizziness or vertigo
    Brief spinning spells, especially when standing quickly.

  • Brain fog
    Difficulty concentrating, forgetfulness or feeling mentally “slowed down.”

  • Head pressure without headache
    A sense of fullness or mild squeezing around the temples or behind the eyes.

Weird Gastrointestinal Indicators

COVID isn’t just a respiratory virus. New variants continue to show stronger GI involvement:

  • Sudden nausea or queasiness
    Feeling queasy without obvious causes like food poisoning.

  • Diarrhea or loose stools
    More frequent than usual, often appearing alongside mild fatigue.

  • Abdominal discomfort or cramping
    Generalized belly aches that differ from menstrual cramps or indigestion.

Skin and Nail Clues

Dermatologic signs can feel odd if you’ve never had them before:

  • “COVID toes” or chilblain-like lesions
    Red or purple bumps on toes (sometimes fingers), itching or mild pain.

  • Hives or urticaria
    Raised, itchy welts appearing in clusters.

  • Patches of skin peeling or discoloration
    Localized areas shedding or turning darker without a known rash cause.

  • Nail changes
    White lines (Mee’s lines) or temporary ridges reflecting a brief disruption when infected.

Odd Cardiovascular and Chest Experiences

Pay attention to new sensations in or around the heart:

  • Heart palpitations
    Skipped beats, fluttering, or awareness of your heartbeat at rest.

  • Mild chest tightness
    A squeeze-like feeling that comes and goes, not necessarily tied to exertion.

  • Rapid heart rate (tachycardia)
    A faster-than-normal pulse without heavy physical activity.

Taste and Smell Twists

Loss of smell/taste was an early hallmark. Now, variant-linked distortions may include:

  • Parosmia (distorted smells)
    Pleasant scents suddenly smell rotten or chemical-like.

  • Phantosmia (phantom smells)
    Detecting odors—like smoke or burnt toast—when nothing’s there.

  • Strange aftertastes
    Metallic or bitter tastes lingering well after eating.

Eye and Mouth Surprises

Watch for unexpected changes in the eyes or mouth:

  • Conjunctivitis (pink eye)
    Red, irritated eyes that may produce a watery discharge.

  • Dry eyes or excessive tearing
    Fluctuating moisture levels in the eyes, sometimes in the same day.

  • Oral ulcers or mouth sores
    Small, painful spots on the tongue, gums, or inside cheeks.

  • Swollen salivary glands
    Tender lumps under the jawline or behind the ears.

When to Take Action

Many of these “weird” symptoms can appear mild or fleeting. However, if you notice:

  • Sudden chest pain or severe palpitations
  • Difficulty breathing or persistent wheezing
  • Confusion, fainting, or severe dizziness
  • High fever that won’t break

…seek medical attention immediately.

Otherwise, if you’re curious about how your symptoms fit together, you might consider doing a free, online symptom check, using the doctor approved Ubie Symptom Checker. It’s quick, confidential, and based on vetted clinical data.

Tips to Stay Safe and Monitor New Signs

  1. Keep a symptom diary
    • Note when each unusual sensation started and any factors that eased or worsened it.
    • Track temperature, heart rate, and oxygen levels if you have a pulse oximeter.

  2. Stay in touch with your primary care provider
    • Send updates via patient portals or telehealth apps.
    • Ask if any new symptoms warrant an in-office visit or additional tests.

  3. Follow public health advice
    • Wear masks in high-risk settings.
    • Keep up with boosters and vaccinations per CDC or WHO guidance.

  4. Maintain general health measures
    • Hydrate, rest, and eat well-balanced meals.
    • Practice stress-relief techniques like gentle stretching or meditation.

Why Early Recognition Matters

Promptly spotting less familiar symptoms can:

  • Lead to faster isolation and reduce spread
  • Trigger timely medical advice or treatment
  • Prevent minor signs from escalating into more serious issues

When to Call Your Doctor

Always err on the side of caution. Contact a healthcare professional if you experience:

  • Any life-threatening or sudden changes in breathing or consciousness
  • Chest pressure that radiates to the jaw, arm, or back
  • Severe, unrelenting headache or vision changes
  • Uncontrolled vomiting or diarrhea leading to dehydration

Your doctor can help interpret symptoms in the context of your overall health and medical history.


Staying informed about what are the weird symptoms of the new covid variant empowers you to act early, protect others, and get the care you need. Remember: if anything feels seriously off, don’t hesitate—speak to a doctor right away.
