I used to have a body that was shedding skin. Not just flaking I am talking chunks falling off. My head scratched so much it felt like I had lice. I never had skin problems pre rsd. I did go to a dermatologist who rx some shampoo with steriod in and some skin cream. I can't recall the name as this was 3 years ago but it really helped a lot. I still get flares but no where like it was. I was dx with seborehic dermititis too. Sorry about spelling. I would see if you can see a dermatologist. It may be from the rsd but a derm treatment could help
