I have invisible bruises that happen all over. It is definitely from the nerve damage. I woke up the other day and felt like I was punched in the face, went to look in the mirror and saw no discoloration. It remained for almost the whole day and finally fizzled out.
I get these spots mostly on my thighs where the biopsy at the time of my test showed significant small fiber damage. This was much worse in the beginning and I thought it was over with but apparently not.
