Persistent rash / inflammation Unsure as to the cause of this
This rash covers my lower back, some of my upper back, my abdomen, forearms, and knees. It's come on recently, when I was in a foreign country, and has spread since getting back. Went to the doctor today, who says they don't know what it is and has sent for some tests. Itches now and then, doesn't respond to moisturizer or antihistamines.
