I get the stabbing lightening strikes in my feet, luckily it is only a couple of times a week. Last week I thought I stepped on a nail, but when I looked nothing was there. I guess if you had that level of pain constantly, you would have to pre-medicate with a lot of strong opiates. Although I have found that opiates have very little effect. Mostly my pain is constant burning in hands and feet radiating up to the knees and elbows.
Only one more month before I get my skin biopsy, to test for SFN. Not that it will help me, as I already know I have it! But maybe the doctor will get something out of it...
