I had exactly the same problem and got the parotid gland
removed (near right ear). It is ten years that this surgery is done, and I'm fine ever since then. The surgery however leaves a scar as the body was cut open. Even I do not have any bad habits, but this happened to me and that too at the age of 17, and got it removed back then itself. I'm now 28, and no side effects.
However the doctor was verifying if there was any hearing loss
, and whether I could urinate properly back then. One side effect is that my ears are not symmetrical now :) Dont worry it is not awkward. This can be made out only when I stare at mirror/ passport-size photograph.
One of my friends suggested me to try homoeopathy, but the surgery was done by then.
