Hey Ravi - I'm so sorry you are still having pain.
I think that your surgeon was overly optimistic when s/he told you that the pain would subside in 2 days. Surgeons tend to significantly underestimate recovery time, and 2 days is definitely WAY too short a period of time to be pain-free, as many of us here learned. You also had quite a bit done, so that will definitely influence the recovery process. I had an LIS and a fistulotomy, but not at the same time! For me, each surgery required about a week for the pain to subside, and two weeks before I felt like I could very gently ease back into an almost normal routine. Also, recovery is definitely up and down. I'm not sure why, but it's not uncommon to have a few good days, and then a more painful day, out of the blue. Things started to stabilize for me by the end of week two, and then there were many more good days than bad until gradulally there were no more painful days (just the odd uncomforatable day) by about three weeks to one month post-op. The pain levels also reduce quite a bit on the bad days too. It's still very early in the game for you, so I don't think you should worry too much just yet, especially with all that you had done.
That said, please remember that you know your body better than anyone else, so you should trust your instincts. If you think that the pain merits a trip to the doc, or a phone call, then definitely do it.
Adam, Summergal and I all had fistulotomies at about the same time. I found our posts, which I've pasted below. Hopefully they will help you get a sense of what recovery was like for us:
