Does cold make carpal tunnel syndrome worse?

Not usually: Carpal tunnel syndrome should not be worse due to temperature or weather.

YES POSSIBLE: Cold weather will make the joints stiff, additional shivering, will cause addional compression to the median nerve in the carpal tunnel resulting the worsening of symptoms.

Positioning your: Hand or arm might make a difference, but i agree with the previous answer on this one. I've had both done, so from personal experience, he is right.

YES cold can make: The symptoms of carpal tunnel feel worse, the median nerve at the wrist has its blood supply disturbed by compression in carpal tunnel. Cold also reduces blood supply to the hands through vasoconstriction a normal responseof the body to conserve heat. The two can act together or synergistically to reduce blood flow even more thus worsen median nerve symptoms. Carpal tunnel can give cold fingers 2.

Cold can make the : Symptoms seem worse. Whether it actually makes the cts worse to a significant degree can't be proven, but with cold comes vasoconstriction of the perpheral circulationand that same circulation brings blood to the nerve in your wrist and hand. Since cts really is an issue of reduced blood flow to median nerve due to pressure, than anything that also reduces blodd flow as cold affects it too.

Cold influences: Circulation, as you try to conserve heat your hand and wrist blood vessels constrict, this can amplify the effect of carpal tunnel as that too involves supression of the blood supply to the median nerve but in response to pressure on the nerve. Your symptoms may be worse but the degree of chronicity is likely not worsened. Add cold to any painful or sensation related hand issue and it feels worse.

No: Cold should not affect cts.

Actually, yes: Nerve conduction speed slows in cold temperatures, and does indeed make carpal tunnel symptoms worse.
