Please: Please see your Dentist or an Oral Surgeon. Pain, bleeding, and/or (as in your case) swelling, deserves immediate attention. Could be innocuous (hopefully) or problematic. To find out you must be physically examined. Please make the call.

See a Dentist: If you have any oral lesion, even asymptomatic and it does not clear in 2-3 weeks, see your dentist and get a professional examination and opinion.
