High complicated anal fistula

Hi I am new to this site but just hoping someone might have some advice. 3 years ago I had sireous pain in my bum check like swelling I went to the doc everyday for a week including out of hours as I was in so much pain Nd they just kept say it will be a internal hemeroid and gave me cream. I went back to the doc again after googling my symptoms and asked if it could be a absess she finaly phoned the hospital I went straight in and had emergancy sergery it was a absess with a complicated high fistula. since then I have had operations every 6months to check it and change the seaton. yesterday I had a op were they were hoping to put in a plug in the hope of fixing it. when I came round from sergery they said they couldn’t put the plug in as the fistula has branched of and they will take biopsy and put me in for a mri. my question is does anyone know why after 3 years it would branch off like that? it must have happened in the last few months as in the last 6 months I had consultant look under General anistetic a mri and a ultra sound and it wasn’t seen then. and dies anyone know what the biopsy will be checking for she said chrones (which I was previously checked for) she said or something else. I was struggling to come round properly after the anistetic so couldn’t understand her properly. I am just gutted as hoped yestreday I had a good chance of being rid of it now I have no idea were I stand

Hi Jess. These things can be quite complicated, but you still have an excellent chance of curing it. They have to figure out whether you have crohn’s. Also a fistula can branch in an an unpredictable manner.
But don’t worry too much, CRSs really know their staff.
You have taken a first very important step which is great. Keep us posted and all the best!
