sweat on right arm only leaving the skin too cool

My right arm sweats and leaves the skin too cool(comparing it with left).I feel it very much abnormal and am afraid of something real troublesome;is there something really wrong I must be worried about?

Hello,
It is natural for sweat to leave the skin cool when it evaporates. If you are having excessive sweating on the right arm, then please get hyperhidrosis ruled out. It may be primary (without known cause and usually starts during childhood or adolescence and persists all life) or secondary (as part of an underlying condition like Hyperthyroidism or similar endocrine diseases and dermatological conditions like eczema, psoriasis).

I think getting a thyroid profile tested in the lab may help and also please consult a dermatologist to find out the confirmatory diagnosis as treatment depends on the same.

I hope it helps. Take care and regards.
