I think you should either ask the dermatologist now or cross that bridge when you come to it. Your symptoms do sound a bit like
rosaceaRhinophyma
Rosacea, but I say that from a distance, and would have to defer to the dermatologists who have seen you and are taking care of you. I really can't be any more specific than that. Your symptoms do not sound as though they are related to any underlying problem, though.
Take care.
