Well, the reason I thought it might be PCOS or IR is b/c they've been really hideous for the past year or so... but then I've been on a low-calorie, low-sugar diet for the past 6 weeks and my white scales have almost disappeared. One elbow is now soft and completely normal again and the other one is only slightly white and has no rough texture (just looks slightly ashy).
I was thinking maybe there was some kind of connection with the sugar/IR/PCOS. I haven't changed soaps and haven't been lotion-ing them (which never helped at all anyway). I mean it's just a huge change. Before they looked like the frosted side of a frosted mini-wheat (no exaggeration) and now they are as soft as the inside of my arm.
Weird!!!!!
Thanks for your replies ladies!
