I only have the numbness and some minor tingling with my neuropathy (not chemo related). I was first given gabapentin but stopped taking it after a week or so because it doesn't do anything for numbness which I found out after my doctor consulted with the rest of my Mayo care team. Can you share a little more about your physical/occupational therapy you had that provided some relief?
