Sorry to hear of your suffering. I can definitely identify with this pain. I was in hospital at the start of November with a peri-anal abscess which was apparently ‘self draining’ but refused to pop after a month of agony. I was put only antibiotics for a week (flagyl and another, both through IV) and was on these for a week before it miraculously popped, exposing a fistula. Depressing stuff, I know. It is so debilitating when you can’t move properly due to the pain and the pressure, and even more depressing when the antibiotics don’t work.
I didn’t have a seton inserted and have been on antibiotics ever since, to try and keep inflammation down. I know this is not a long term solution and to be honest I am scared as anything of coming off these antibiotics. The flagyl made me SO SO sick, I was on it a couple of days before going into the hospital and it had me bed-ridden and nauseas. In the hospital, it made my blood pressure drop so low I was on the verge of passing out every time I stood up. I have started on the flagyl again today and hope that it is not so severe on me this time. I have heard flagyl is good for healing fistulas, so desperation has led me to try the killer-med again. I know it does not have a negative effect on everyone, but it made me so sick during and prior to hospital!
My GI is pretty hopeless with the abscess, and has not even taken a look at it, let alone referred me to a surgeon. I hope you have a better doctor take care of you, and that you have some relief soon, via a seton or drugs that work. I am with you and feel your pain, I am similarly miserable and scared, especially since I am job hunting for a new job at the moment too.
