I'm experiencing acute pain 13 days after carpal tunnel surgery in my left hand. i'm wondering if i should go get it checked? appearance is normal.

Pain hand: Acute pain, yes there can be an infection or another issue, call your doctor. Other things such as arthritis at th base of the thumb, or irritation from prolonged dependency on splints may be suspect as well. By speaking to your surgeon directly they can determine if anything else needs to be done. Often this can simply be a phone call but you must call to start the evaluation process

Yes: If your pain is getting worse and not better, I would definitely let your surgeon know.
