Need doctors exam. There is no way to be certain what is occurring to cause your symptoms. A virus or a reaction to food or medicine or another irritant or allergen could be to blame.

See your doctor. You should discuss with your doctor and consider seeing a dermatologist. It is possible that it is an allergy.
Yeast? Yeast is a common offender around the mouth, and if you have used a lot of steroids, and have excessively moist skin around the mouth (such as with lip licking), then yeast will thrive. It's also possible that you have used so many things on the skin that it's chronically irritated. Plain lanolin is probably the best to protect and not irritate. Unlikely to represent food allergy.
