We first have to search for the cause responsible for the granuloma. There are many reason for granuloma to occur. eg TB can cause granuloma. So in this case treating the TB can cure the granuloma. I advice you to do microscopic examination of the material conning out of the granuloma. Once the report available you can get the treatment of the cause done.
