Hi, I have a problem were I have a fluid filled lump under my scalp that is about 2' in diameter. It is mushy to touch and clear fluid comes out when I squeeze it. It actually started on the right side of my head and now is in the back of my head. It is very sore but that could be from me squeezing the fluid out. It kind of started like pimples but now is like the diameter of a golf ball. You can actually move the liquid by pushing your scalp in one direction.
