I am 64 years old, and in the last year or so get lumps on my upper back about the size of a nickel.  They are hard in the middle and sometimes itch.My husband has lanced 2 of them found a hard white somewhat oozy substance in side.  The latest one he did is healing slow and the skin around it is white about a 1/2 inch all around,  what could this be?
