Yes, that sounds very familiar to me too. Dermatologists in general seem to be missing the point when it comes to treating acne, though given the nature of the disorder, thats hardly surprising. I agree with what #39736 said about seeing a naturopath. They, in general have a far better understanding of the body as a whole and hence, are far better at treating this type dissorder effectively and getting to the root of the problem.
Just a couple of questions for you: What steps/processes have you tried so far, and what results did you see?
Have you taken any drugs or medications?
Have you done any allergy testing eg. kinesiology?
