I've had a small bump on the my left side for about a year. About 6 weeks agao the bump became real large and sore and swollen. It did not have a head like a pimple but after a couple of weeks the bump opened up and I had two round like open sores the oozed a think blood like substance.
I put antibiotic cream on it and it has not gotten smaller and the swelling has gone. The sores have not completely gone away and will open up and ooz a little. The sore is about 1 1/2 " in diameter and dark purple in color. It has now been about two months and it doesn't seem to heal.
