My daughter is 26 and is just getting over the shingles. They were located on the lower left side of her back. She has now discovered a marble size lump on the same side. Could this be caused by the shingles or is this something else we should be concerned about? Sandy

I would get it checked out. I had shingles a couple of years ago with no lumps emerging at any time. It could be a cyst of some sort -- malignant or benign, water-filled or infected. Does the lump hurt in any way?
