I've had an anal fissure for about 8 months now with an 8mm mass near the front. It only hurts during bowel movements when my stool is hard, otherwise no pain at all, but there's a little pus at the site. Do I need surgery for this? If so, what are the side effects? Would lateral internal sphincterotomy (LIS) be recommended and what are its side effects?

Given the presence of an anal fissure for 8 months, a mass, pain during hard stools, and pus, surgery might be needed to address the chronic nature of the issue and potential infection. Lateral internal sphincterotomy (LIS) is a surgical option but it's crucial to discuss its risks and benefits with a doctor, including the possibility of sphincter incontinence.

I'm experiencing this strange pain in my bottom when I sit for a long time. It really burns, but interestingly, when I stand, run, or sleep, the pain goes away. I don't feel any pain or see blood when I go to the toilet, although I am dealing with a little constipation. There's no blood or pus in my stool either. Some people are telling me it might be piles, others say it could be fissures or maybe even a fistula. I'm really confused and would appreciate some guidance on what this might be.

I'm dealing with piles, but they haven't been painful at all. My doctor has mentioned surgery as an option, but I'm wondering if I should try medication first. What do you think? Should I consider other treatments before jumping into surgery?
