Well that explains a lot. I thought it was result of chemo but not sure now. The three end toes on each foot were very numb. It's been about a month maybe 6 weeks. I was having balance issues and even fell a couple times. I tried a back brace and almost immediately the feeling started coming back in my toes. I slept in it a couple nights. Now I know it's back related and will discuss it further with pain doc.
