question: I have a large lump on the right side of my neck, right by the hair line, close to my spine. I thought it was a knot, so I had a couple people try to rub it out. It didn t work. Today I found another lump a couple inches higher on my head. I am on Topamax and Imatrex for my migranes, and the past week they have been getting worse. I don t know if they are linked or these lumps are serious. Any advice?
