For years I’ve spent hours at a computer contributing to numbness, tingling, and pain in my hands and lower arms. I do have PN, but my hand issues started developing prior to my diagnosis. I found at least some relief and better mobility by going to occupational therapy. They gave me a stack of exercises, some stretch bands, and therapy putty. As I have to use a computer for work, I continue to do the exercises on my own and find they definitely help. Good luck with your pursuit for a confirmed diagnosis and treatment!
