Lesions in the anal area can lead to infection, whether you actually have a STD or not. Regardless, colloidal silver could help clear it up administered anally via either an enemes which you hold in for awhile before expelling or via a rectal syringe. You should also take PLENTY of colloidal silver orally throughout the day and it might be a good idea to also take oil of oregano (you can buy it in gel caps) and olive leaf extract.
