Someone told me to try an ice pack or extremely cold water in a wash cloth(squeeze out the water) and apply it to the areas where you get numb. It worked when my right arm went numb! See if that helps you!

Get a referral to start going to physical therapy.

I've heard some docs prescribe Amitriptyline
Brand name: Elavil. Purpose:
Antidepressant and Nerve pain medication
It can treat depression. I didn't care for it, but it has reportedly worked well for others. Good luck.

Anti depression med wow...what med did he put you on ?
If it works and gets rid of the itching, more power to you !!😀

I agree with ElizabethCorey.
The exercises seem to work for me as well.
