How about delapidators (sp?) there are some that are for sensitive skin.. I tried them long ago and it was chemicaly painful but aparently they are alot better now. (my skin has always been sensitive too)

I kept up my leg shaving through the pain and I realy think it has been like ongoing desensitizing of my legs, I had to let them grow when I was so bad again this winter and my leg sensitivity went way up (also felt like lotsa ants were crawling all over on my lower legs alot)

I noticed my legs are more sensitive again since but I consider me continuing to shave is part of my therapy physio too.

I have a flat air matress pillow that floats well with the leg I am shaving on it, and it also seems to help alot with the chest wall pain cause it brings your leg closer. and always make sure the legs are real warm first.
