M.G.
Keep us posted - sorry you are going through this
I was going to say have you had an EMG done? That's a helpful test. My husband has carpel tunnel and also degenerative disk disease. He gets tingling, burning and weakness also. Usually in one arm and hand - he wears a brace at night to keep his wrist and hand in a position to minimize the tingling. Otherwise he wakes up.
Posture is a biggie.
I have a neurological condition. One of the things they ruled out early on was MS. I don't want to alarm you unnecessarily, because there are plenty of other symptoms of MS you don't mention. For me, I lost my vision so that's why they tested me for it. It shows up on an MRI.
I hope you get some answers today from talking to your doctor. Good luck :) wishing you well
