Hi! Thanks for the query. With the symptoms that you have mentioned, I think you either have an aphthous ulcer or a submucous retention cyst
. An aphthous ulcer will heal on its own and is caused by stress
. Just take some multivitamin
tablets and Smyle gel which is available over the counter. In case the swelling doesn't subside within a week ofits onset, you may need to consult a surgeon. Antiinflammatory medications such as diclofenac
will help in relieving the pain.
