A dermatologist was going to remove a pilar cyst from my scalp that I've had for 25 years. It was getting sensitive and about 3.5 cm large. When he opened it, he discovered it was actually a lipoma. He performed the procedure anyway and I'm wondering if a dermatologist is really trained in this kind of surgery? It took about 40 minutes to get it out. Today is the 2nd day and I'm getting bad headaches. I've had 5 stitches inside and 7 on top.
