Hello I have a large boil/cyst on my waistline, these are reoccurring but this bar far is the worst and mist painful. It has drained some on its own, i have applied neosporin ointment and bandage and I allow it to breath while I sleep at night. Its the size of a nickel,very red and has 3 holes with in it, i can also feel infection around the boil aswell. It has an intense burning sensation as well, what is causing it? Is there anything. I can do from home?
