About 7 weeks ago, I was eating outside, when all of a sudden I felt my lower lip swell. At that very moment, there was a wasp buzzing around my face so I immediately thought it may have been a sting, even though it didn't hurt. It was only swollen to a small lump on one side, and looked a bit like a blood blister. It got slightly bigger throughout the day, but since then gets bigger and smaller in size, depending on whether I accidently bite it or not! The blood has disappeared and it now just looks like a weird bump on my lip, I can feel its full of fluid. Its not painful but does feel a bit like a bruise. All the doctor gave me was hydrocortisone cream to use for a week which hasn't worked. And now she says there's nothing else she can do! I work in the performing arts so its very insightly and is affecting my confidence. Any suggestions?!
