Has anyone been on CellCept for a period of 8 or more years? I noticed a couple of months ago that a 3 to 4 in long and finger width lump has appeared on the top of my scalp. I've always had headaches, but they seem to be increasing w/weird burning and tightness mild ache in the area of bump. I've had to have a cyst removed from scalp and Sternum area one other time, way before Lupus diagnosis but feel pretty paralyzed to go to dr about it since CellCept can produce a deadly brain infection. Should I just ignore it as a cyst? This is much harder then the cyst was.
