Few days before i got a pimple on my hips which later became very severe and currently it is round and red with a fluid on top which bursted last night and there was a bit of blood . And i am facing severe pain after looking over i found that it may be a boil.so what should i do now should i consult a doctor or put some cream and leave it ?? * Should i apply Mupirocin ointment I.P 2% on the boil , which was given by local clinic shop.
