question: I have a pea-sized lump in between my shoulder and neck. (left side) I asked my doctor about it months ago, and she said that it's nothing to worry about it will go away over time. It's been almost a year since I've had it. It looks like its filled with puss...there is no pain though. I've tried putting a face cloth dipped in hot water on it to try and drain it. But it doesn't do anything. Should I be worried?
