it sucks huh!
Mine developed about a week post c section, luckily (or not) I was still in hospital then (due to JJ being in SCBU) so they kept me in while they trialled various antibiotics to try to fix it. The first two they tried didn't seem to work but the 3rd one did the trick. It was sore and really red and horrible looking.
They tried to open up the wound to wick out the infection but that didn't want to work, finally one night I worked out a way to prop me up with pillows in the right places so I could sleep on my stomach (just cos I wanted to, nothing to do with the wound infection!) and the heat and pressure seemed to do something. Sorry, TMI: I woke up at 3am oozing out of the wound all over the sheets etc and buzzed them, they were all excited that it was finally being drawn out, one of the midwives and I spent about half an hour pushing and squeezing it to try to get as much as we could out of it.
A wound nurse that stopped by the next day commented that a poultice would have done the same thing (not that anyone suggested it, a bit too alternative), so maybe that's something to look into? Even just putting a heat pack on it perhaps?
Hope it comes right soon, that's a long time for it to be hanging around
NB there was a girl in my antenatal class who had a similar thing only they eventually decided to take her back into theatre, open her back up and clear it out
hope it doesn't end up that way for you!
