Hi Mikayla, I have had 2 surgeries for fissures and I can sympathize with you. Only 50% of people can heal them on their own. I sat on a "donut" for 14 years. During one of the surgeries, the doc hit my pudendal nerve, hence the sitting problem. I took an anti-seizure medicine off label for an unrelated problem and in 2 weeks the pain was gone. It was Topamax. My PT said she had heard it works. You might want to ask your doctor.
