Carpal tunnel syndrome: symptoms, splints and next steps
Updated: Oct 15

Carpal tunnel syndrome is compression of the median nerve as it passes through a narrow space at the wrist. It can cause tingling, numbness, pain or weakness. Other conditions can cause hand symptoms, so the pattern needs assessment.
Recognising the symptoms
Symptoms commonly affect the thumb, index and middle fingers and part of the ring finger. They may wake you at night or occur when the wrist is held bent. Some people notice an aching hand or forearm, difficulty gripping, or a weak thumb.
The little finger is usually supplied by a different nerve. Symptoms there, neck-related pain or a different pattern may need another explanation. Do not diagnose a trapped nerve solely from a diagram or finger pattern.
When to seek assessment
See your GP if symptoms are worsening, not going away or not responding to home measures. Persistent numbness, loss of grip, dropping objects or visible loss of muscle at the base of the thumb should be assessed promptly.
Sudden arm weakness with facial drooping or speech difficulty needs 999. Severe injury, a change in hand or arm shape, or sudden loss of feeling needs urgent assessment. See the arm and hand guide for help with other symptoms.
Why can it happen?
Often there is no single identifiable cause. Pregnancy, diabetes, arthritis and previous wrist injury can be relevant. Repeated hard gripping, vibrating tools or prolonged wrist bending may aggravate symptoms.
Computer discomfort does not by itself establish carpal tunnel syndrome or prove that the keyboard caused it. Review your setup for comfort and reduce prolonged pressure on the wrist, while arranging assessment if symptoms persist.
Symptoms during pregnancy should be discussed with your midwife, GP or treating team; they often improve afterwards but still need attention if severe or progressive.
Wrist splints and everyday changes
A night splint that keeps the wrist straight can help some people, especially when symptoms disturb sleep. A pharmacist or clinician can advise on a suitable fit. It may take several weeks to judge the benefit; do not delay medical review for worsening numbness or weakness while waiting.
Reduce repeated hard gripping or wrist bending where possible, vary tasks and take breaks from activities that provoke symptoms. A comfortable desk arrangement may make work easier.
Pain medicines can sometimes help discomfort but do not remove nerve compression. Hand exercises have limited supporting evidence and should be appropriate to the assessment, rather than repeatedly provoking tingling.
Medical treatment choices
A clinician will ask about the symptoms and examine the hand. Nerve-conduction tests, and sometimes imaging, may be considered when the diagnosis or severity is uncertain; not everyone needs them.
A steroid injection may be offered when a splint has not helped enough, although symptoms can return. Carpal tunnel release surgery may be considered for persistent or more severe problems. Discuss likely benefits, risks, recovery and the consequences of waiting with the treating team.
The NHS England decision aid can help prepare questions about these options.
Where osteopathic care fits
Andy can assess related muscle and joint symptoms and discuss activity changes or referral. Osteopathic treatment cannot be relied on to relieve pressure on the median nerve, reverse nerve damage or replace a medical treatment that is needed.
If treatment is offered for an associated problem, agree its purpose and review whether it helps. Increasing hand weakness or persistent loss of sensation should lead to medical reassessment, not an open-ended course of hands-on treatment.
