I agree with Megan, with the baffling part. I am 3 years post PN, they beleive it was a once off autoimmune reaction with me, and I still have odd things going one that I cannot explain.

3 nights ago I woke up with leg cramps so severe in both calfs, I was in severe pain. This was at 3 am,and then I was up all night with pain.My legs still hurt. I am trying magnesium/calcium and I eat banannas yet I have leg cramps 4 x a week on average with no evidence of anything but small fibre neuropathy, and really no evidence of that either except subjective clinical.
