I ve had an infection got 3 months that started as a boil. Kefkex made it smaller but not gone . I just had a surgeon remove an infected cyst three weeks ago and it is draing yellow serous fluid. I went back to the surgeon today and he said just to wash with soap and water. I asked if it could be mrsa and he said that it would be deeper. But there are two holes that are draining and they look deep to me. He says that it isn t healing because it is at my waist and the elastic is causing it not to heal. I think I have mrsa because it started 3 months ago and it looks like the pictures I saw on the web. I have been using colloidal silver topically and it helps but doesn t take it away.
