I have 2 lumps close together on the crown of my head. They are hard, and have been there for several years. This week however, I noticed that one lump has become larger and it was a little sore to the touch. I got a hair transplant in 2009, and they were there at that time, but smaller. I mentioned it to the doctor, and he shrugged it off as no issue. I also had a closed head injury at 18, and in a coma for 13 days. I am 59...white male.
