I have a rash on my lips(mouth) for almost 2 years. No one can seem to diagnose or find a cure for it. They claim eczema, but they seem to use this for eveything they don't know whats it is. I don't believe this eczema, it is not in the family I have never had this problem, and in a rare are the lips. I have done every test know to man, and the following have been ruled out, virus, herpes, fungal, yeast, perioral dermatitis, etc.. Keep getting staph infections from the issue, have taken antibiotics doxicyclin, bactrim ds, and famvir for viral, used cortisones creams, elidel creams, yeast/fungal cream, vaseline, taken vitamins, oral predisone. Nothing is wokring. My lips get sore, dry , start to get little bumps on them, gets a little crusty, gets inflamed and irritated. Tests have been done for autoimmune diseases, Thyroid, blood work, all seems to be negative.
Any ideas what else it could be or tests that should be run? How do I cure?
