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..
