I saw a doctor yesterday for a boil on my armpit (dealing with MRSA). I thought he would’ve lanced it with it being quite big, but he prescribed doxycycline and said that it should help drain it. But wouldn’t it need to get lanced first and then the antibiotic clears up the infection? Can this antibiotic actually help clear it up without lancing? And, if it wouldn’t, would it mean that my body is immune to it or it’s not effective?
