I've had this abscess/boil for over 3 weeks now, it's not coming to a head and is just getting bigger and more painful. I've tried magnesium sulphate paste and a dressing for a few days, nothing happened, I soak in a hot bath every day but that's not bringing it to the surface either and I've tried a hot flannel. Any suggestions because it's really hurting, and this is my comfy pyjama bra but all my other ones the metal underwire digs right in to it
