I have a clear bubble on the top of my mouth near my uvula , there is pain and it hurts when i swallow what could it be?

Bump in the throat: How long it has been there? Do you have fever? If it has been there for more than 7-10 days you should see your doctor. It could be strep throat or mononucleosis.

Exam needed: This could be a burn from hit food, a canker sore or a herpes virus lesion. For diagnosis and treatment a physician or otolaryngologist would have to examine you.

I'm sorry: Not enough room to list all the possibilities. Nd not being able to examine you it would only be a guess. Please see your Dentist for an examination.
