I got a perianal lump. i am taking augmentin (amoxicillin and clavulanate) and it is not helping. what esle can i do without going for op? cos i just had a baby 1 week ago

You need a surgeon: It is likely that you have a peri-rectal abscess which is a well defined medical condition, best treated with drainage(Incision and Drain). it is not a major operation but one that is necessary. Abscesses rarely heal with antibiotics...they tend to rupture and can create a fistula which is much more complicated to treat later on. So you can seek 2 opinions quickly(today/tomorrow) and settle for 1.
