Hello @jeanner7, Welcome to Connect. Neuropathy or arthritis is a good question but it's something a doctor needs diagnose with some testing and an exam in my non medical opinion. Here is some information that might help explain what might be happening.

"There is a link between RA and carpal tunnel syndrome, a mild form of neuropathy involving nerve damage. The main symptom of carpal tunnel is numbness and tingling in the hand and fingers."
