As far as your skin issues go, have you checked to see if you have Psoriasis or Ecxema? If so, and you don't have either you may also check on this. I have a couple of clients that come into my Salon that have the bumps that I think you are talking about and one of them said her Dermatologist checked her Hormone levels and I think it was the testosterone levels were wacked out and this was her problem. The reason I mentioned Psoriasis is that it comes and goes. Certian things can make it flair up, weather, stress, foods. It is not curable but you can calm it down. There are so many things that can be diagnosis, Thyroid levels are a big one with hair loss and symptoms like you are talking about. Just a thought!
