Re: How to tell the difference between CTS vs. Ulnar nerve entrapment?
Carpal tunnel affects the thumb, index and middle finger, ulnar nerve entrapment affects the ring side of middle finger, the ring finger and the pinky. The pain can be similar, I have both, but with my CT I didn't have numbness just cramping and weakness throught the palm and up the wrist just a little. With the ulnar it is burning pain up the pinky finger down through the hand and up the arm sometimes on the pinky side of arm and hand. I had CTS on the right and CTS and ulnar decompression on the left which was unsuccessful and I'm left with nerve damage not repairable. It has been a year since the ulnar and my middle and ring figer are still sensitive, prickly and burn at the tips of which I still seek physical rehab everyday.
