i used to have very sensitive skin just after dx, to the point that i had to have my hair washed for me at a salon, and i had to go out and buy a bunch of lounge wear because i couldn't tolerate my jeans.
i don't know what specifically fixed it, because it slowly resolved over a long time, 6 months or so. lets say 3 months for body, and another 3 for the hands. that was in the first half of 2006.
i had to change my diet and start taking supplements. seems to have turned things around. could be coincidence. certainly with other situations i have noticed far more dramatic improvements (i.e. over a few days) when adding one supplement or another.
