Surgery/Post Surgery Recommendations?

Hi everyone!

History: I have multiple anal fissures that I’ve been dealing with since beginning of January this year. The first few months were completely debilitating until I saw the CRS and was prescribed nifedipine 0.4%/ lidocaine 5% ointment. Once I started using that, my pain went from 10/10 for 10-16 hours after BM, to only having 2-3/10 immediately after BM. I have had a couple retears that obviously restarted the process.

Present: I saw my CRS a week ago and again denied the anoscopy because the fear of retearing is crazy. But, he was able to do a digital exam and rubbed over a certain area right inside the anal opening and when I said that hurt, he told me there is an infection there and I have to have surgery now. He says he still cannot see the fissures (but u know that’s what they are - my daughter has had them since she was an infant). He believes they are more “inside” based on what he could feel. Nonetheless he says that surgery is imminent now but is not fully sure what all he will have to do in there. I told him I know that I have hemorrhoids and I DO NOT want that surgery but he said if the infection is attached to them, he will have to. But, he explained a fissurotomy and LIS to me and said it would likely be one of those surgerys and draining the infection.

My questions: What are the things that I should absolutely have for my recovery? What recommendations to aid in healing? I truly do not know what to prepare for and I am terrified of the surgeries and the pain afterwards if it is anything like the pain I had the first four months of this year (was so bad I literally so bad I would be crying for hours on end begging God to make it stop). Apparently, I won’t be able to use the nifedipine ointment after, so that scares me too.

Any recommendations are welcome and thank you so much for even taking the time to read this.
