I had a boil a couple weeks ago, came to head and drained on it's own. this past week i got another one right below and it finally popped but, there's a hard red lump now above my new boil. could another one be returning? while one is still draining?

Boils: When boils come in crops it indicates that the skin at the involved site is colonized by staph bacteria which are becoming invasive. In my experience this calls for a course of potent antistaphyloccal antibiotic given orally for 10-14 days. In addition keep the surrounding skin sterilized with rubbing alcohol and keep it protected from pus by covering the active boils with gauze and paper tape.
