looks that you are the only one after few years who is active now.
I ve been reading this site several times after my surgery when I had any doubts about my healing.
Please note I m not a native speaker so my English will be simple.
So my long story short...
I ve been on 5 surgeries all together. In my case it started with inflammation of bartholins gland as a gynecologic problem. it was in 2014. The gynecologist extracted it but it was really deep and complicated. Treatment took really long time. I was not able to sit comfortable at least 4-5 months. After one year inflammation was back. surgeon thought that it just did not heal properly so he cleaned it again...again pain and treatment. But after 10 months the same story and another surgery.
Just in the end of last year when it happened again I had the feeling it is not just about the old wound but I had the feeling that it has connection to anal.
After several examination and MR I found the specialized surgeon. During the surgery he confirmed that it is perianal fistula communicating between old wound and anal (that's why it was never healed properly before).
So it was in January. He cleaned fistula and made ligature (do not know if it is right word in English. basically he inserted tiny thread going through the fistula. As I understood the purpose was to heal it just thickness of the thread). The next step was advanced flap surgery. It was done in May this year.
Have to say that I thought it will be less painfull. I thought that the first one was more difficult...but first two weeks were horrible. went to the toilet with tears in my eyes.
After more that 3 months it is still not healed properly. It pass gas and discharge after using toilet. I went to the doctor before two weeks and he inserted the thread into fistula again. Hoping the connection became less wide.
Nevertheless I still have some hope that it will heal. Making baths with herbs. Also my doctor said when I went for holiday that sea is really good for healing. So I continue making baths also with salt. And in 3 weeks go for another holiday. So hope It will help again. At least for psychic.
Now I am trying to find any recommendations. I read that the food is really important. Less sugar and also carbohydrates, lot of vegetable. Also I am trying to find some info about Ayurveda. From medical point everything what was possible was done. So now I am thinking to go more natural way. To make body more powerfull to fight with inflammation. At least I can try it
Despite I do not know if it will be healed I am trying to live normally if it is possible. Going for holidays, festivals... For last years I missed a lot of things because of the fistula. Do not want to do it again.
Reading your story I can imagine how you feel. But it will be better and better day by day. Hope that you are the lucky one and advanced flap will help you finally.
