Suggest Treatment For Swelling In The Legs

Hello, I have been experiencing swelling of my ankles, feet, and lower legs. lasting for several days. I recently had 2 bumps appear on each leg and one on top of my left foot. they felt hard to the touch but skin scratched off easily revealing a pus center, I had one that appeared to be a blister. I cleaned them well applied neosporin and band-aids. They did not produce any more pus but are still slightly red and seem to be healing slow. Last evening on lower unside of my left breast I found a round bump like knot about the size of a marble and tender to the touch. Today I was examining this and barely compressed the area and puss came out, cleaning with peroxide and cotton ball more puss came out and there appeared to be a head in center. I covered with a band-aid. my legs are not swollen at this time. I recently visited a friend s mother in the hospital. I am concerned. I have not experienced any fever, but I have been very fatigued.
