Thank you for taking my question. My son, age 34, has a mole on the back of his scalp. He is fair-skinned and the mole is about the size, shape, and color of a small beige pencil eraser. About a month ago he said he hit it with his razor while shaving his head. Now it seems to be sitting on a little, pink, puffy swelling about the size of a nickel under and around the mole. The pink area is not hard but softish. Should he have it drained?
