About two weeks ago, I had a sore knot arise under my breast where my bra line is. I thought it was a boil because of the pain, but after treating it for a week the pain went away but the knot has doubled in size, is raised, and fixed. It has now been a little over two weeks and the knot is now the size of a quarter. I am very concerned. I had blood test ran right after the knot came up that showed my wbc count to be high and my feet have been swelling. Should I be alarmed that this could possibly be more than a lymph infection
