The short answer
Carpal tunnel syndrome occurs when the median nerve is compressed at the wrist. It can cause tingling, numbness, pain or weakness in the hand, often troublesome at night. Other nerve problems can produce similar symptoms.
Understanding the problem
An assessment checks the distribution of altered sensation and how hand function is affected. The clinician may recommend nerve tests when appropriate. Persistent weakness, dropping objects or worsening numbness should be mentioned promptly rather than dismissed as ordinary fatigue from computer work.
Care and next steps
Treatment can include a wrist splint, activity changes, an injection or surgery in selected cases. The choice depends on severity and response to earlier care. Do not assume that every tingling hand needs an operation or that a splint will resolve every nerve problem.
Prepare for your consultation
Note which fingers are affected, whether symptoms wake you and what relieves them. Describe difficulty with buttons, writing or holding small objects. Bring existing test reports and any wrist support. Ask what improvement to expect from the proposed treatment and what would signal that it is not enough. If work modifications are needed, request clear instructions that your employer can understand.
Common questions
Does hand tingling always come from the wrist?
No. Nerve symptoms can have other causes. Examination helps decide whether carpal tunnel syndrome is the likely explanation.
