I had an infected cyst on my back, years ago now. I showed it to my doc. He said, “Yup, that needs to come out. But it is too infected right now, so here is a perscription for some antibiotics”. I got the antibiotics, and took them like a good girl. But I also put an epsom salt poultice on it at night, taped into place. When I went back for the thing to be removed, the doc was VERY impressed with how much it had cooled out, looked far better than he thought it would. He removed it with the superficial surgery in his office. I knew this doc for a long time, he was a bit of a family friend. I sent a lot of horse owning people to him as patients with my recommendation. He told me that he loved working on horse people. He said that they came in with the most horrific looking things, injuries etc, which the first thing they told him was that they had been treating it themselves, with horse medication, and it was looking WAY BETTER now that he was seeing it. This doc learned was “vet wrap” was.
PS- OP, you need to take your issue to you doc, it is not something that you should be treating without professional input and guidance.
