About 5 days ago I discovered a lump on the right side in my neck. It is painful to the touch and when I look to the left and swallow, it hurts. I know it can't be my thyroid because I had that removed 2 years ago. It seems to be about the size of a marble. Since Cancer runs in my family, I am a little freaked out about it. Unfortunately, I am a smoker-- but not a "chain smoker". A pack will last me 2-3 days. Anyway, just wondering if I need to go see my doctor or my endocrinologist about this. Not sure what to do or if I need to do anything at all.
