Eval needed: The only way your question can be answered is by actually seeing your mouth. See a dentist to have this area checked. There are many things that it could be.

See a dentist: If if the lamp lasts longer than one or two weeks, you should be concerned. I would advise you to have the lump examined by a dentist or dental specialist (e.g. pedodontist, oral surgeon), to help you with a diagnosis and treatment, if needed.
