Hi Leslie, If it doesn't go away in a couple of days, definitely have it looked at. Don't want to scare you or anything, but my husband had Hodgkin's Disease many years ago and the first sign was a lump in his neck. His lump fairly large, though. Also, I don't know if you drink beer or not and this may sound weird. But if you drink a beer and feel a burning sensation throughout your neck and chest, get to the doctor quick. That is a sign of Hodgkin's. On my husband's first trip to the specialist, the first question the doctor asked was if it burned when he drank alcohol. Weird huh? Sure enough, it did burn. To this day, my husband doesn't drink alcohol. I think he's scared to.
I wanted to add that chances are it is nothing or it could just be a cyst that needs to be drained. After I wrote the above paragraph, I thought I might have scared you and wanted to say more. Sorry if I did scare you.
