Hi, I noticed a hard lump on the back of my head, about 1 to the right of the middle of the back of the head and about 2 above my hairline. It s smaller than a dime, raised and hard, non-moving and not painful. It showed up a couple of weeks ago. I am a 47 y/o female. I have had 3 consecutive blood tests where calcium has been out of range (10.5, 10.6, 10.5). Had my PTH and vitamin D checked, the PTH was in range but at the higher end, and Vitamin D was out of range at 30. I suspect I may have a parathyroid issue. Could the bump be related? If not, any thoughts on what this might be? Thank you, Chris
