I Probably Hav Sarcoidosis Of The Nevous System. I Say

I probably hav sarcoidosis of the Nevous system. I say probably, b/c I've had my health problems for three years with no real difinitive diagnosis, literally, I am thee International Man of Mystery. All that being said, I was on 60mgs of Prednisone for about six months. I hav a very comprimised immune system and hav had thus foliculitis for four months??? I just wanna kno if it can feel more itchy in bed or if or is a heat thing? Nothing, antibiotics/topical has worked to help it and it continues to spread over more of my body as time goes on. Can u answer those Q's my friend? Thanx & Blessings!
