before I wrote mine. I didn't know you had already been to doctors. Don't let the people on here get you down. I just think they want to see photos. Why don't you upload some? Skin diseases are many and we can't possibly tell what you have w/out ast least seeing them.
Doctors are not all 110% useless. Lives have been saved thru them. I was even under general anesthesia under one and he brought me back to consciousness well and able to carry on with life. So they are good for something.
It is just hard sometimes to figure out what someone has if the doctor doesn't come in contact with that too often. Tell me more about your condition, symptoms etc.
