The carpal tunnel is an area in the wrist where nerves travel. When the tunnel is compressed, symptoms of numbness or pain in the fingers can occur. Common triggers include long periods of typing on keyboards, pregnancy, and diseases like rheumatoid arthritis.
Your doctor may ask these questions to check for this disease:
Mild cases can improve with painkillers and rest with a splint. Sometimes, a steroid injection to the carpal tunnel may be helpful. Severe cases may require minor surgery. Treatment continues with physical therapy to improve muscle strength and relieve symptoms.

Q.
Carpal Tunnel? Why Your Hand Is Tingling and Medically Approved Steps
A.
Hand tingling, numbness, and nighttime waking are often caused by carpal tunnel syndrome from median nerve compression, and most cases improve with medically approved steps like activity modification, nighttime wrist splints, short courses of NSAIDs or a corticosteroid injection, therapy, and surgery when severe. There are several factors to consider, including other conditions that mimic it, risk factors, and urgent red flags; see below for the full checklist, prevention tips, diagnosis options, and guidance on when to see a doctor so you can choose the right next step.

Q.
Hand Numbness? Why Your Wrist Has Carpal Tunnel & Medical Next Steps
A.
Hand numbness, tingling, or weakness in the thumb, index, and middle fingers is often carpal tunnel from median nerve compression; first steps are night wrist splints, activity and ergonomic changes, short-term anti-inflammatories, and sometimes a steroid injection, with surgery considered if symptoms persist, are severe, or cause weakness to avoid permanent damage. There are several factors and look-alike conditions to consider, including diabetes, thyroid disease, pregnancy, neck pinched nerves, and ulnar nerve problems. Seek emergency care for sudden numbness with facial droop, arm weakness, speech trouble, or a severe headache, and see the complete next-step guide below to decide when to get evaluated and which treatments fit best.

Q.
"Electric" Hand Pain? Why Your Wrist Is Sending Shocks & Medically Approved Next Steps
A.
Electric, shock-like pain in the hand is usually nerve related, most often carpal tunnel from median nerve compression that affects the thumb, index, middle, and half of the ring finger and often worsens at night, though other causes like a pinched neck nerve, ulnar nerve compression, or neuropathy are possible. There are several factors to consider, and medically approved next steps range from night wrist splints and ergonomic changes to anti inflammatory treatments, therapy, and sometimes surgery, with urgent red flags like sudden arm weakness or stroke-like symptoms needing immediate care, so see the complete guidance and what to do next below.

Q.
Hand Zapping? Why Your Wrist is Numb & Medical Carpal Tunnel Steps
A.
A zapping or numb feeling in the thumb, index, middle, and part of the ring finger often points to carpal tunnel from median nerve compression, often worse at night, with risks from repetitive use, diabetes or thyroid disease, pregnancy, and wrist anatomy. Diagnosis uses your history, an exam, and sometimes nerve tests, and treatment steps progress from night wrist splints and ergonomic changes to NSAIDs or steroid injections, therapy, and surgery if symptoms are severe or persistent; knowing when to seek care is crucial. There are several factors to consider, and important details that could change your next steps are explained below.
