Just about 2 months ago I began developing strange allergic reactions. They have occurred on my feet, hands, back of knee, upper thigh, lip
and now tongue. I have gone to the doctor before and they said it was contact dermatitis. I have not figured out what I'm allergic to yet and am still waiting for a call back from the allergy department. Last night, I woke up at about 3am with a swollen tongue. It really freaked me out.
