Hey Arafat! I'm so happy you are doing so well!

Yippeee!!!
You're very welcome, of course :D
Life without pain is so wonderful. I know I'm not going to take that for granted again. :D I think you are doing great, especially for six weeks out. Scar tissue can cause some discomfort, but it does settle down after a while as the tissue softens. I had some very minor drainage for about six months after my fistulotomy, just wound exudate, but that's stopped now. These things take a long time to completely resolve, as you know, so it is really great that you are so patient and you know what you are doing. At the rate you are going, I'm convinced you will be 100% again soon. You're a great example for others here. :D
Fistulaproblems - I'm very glad that you have such a good new CRS. I was wondering if you would get a seton, and I'm glad you did. From what I've read, that is the safest way to go for deeper fistulas. I'm also really glad you are getting tested. I did a lot of research on fistulas when I had mine, and I didn't see anything about fistulas, by themselves, being caused by cancer. Of course, I'm not a doctor, so everything I say has to be taken with a grain of salt :) But I think I'd put cancer pretty far down on my list of things to be concerned about just now. There is such a thing as peri-anal crohns, which can be difficult to diagnose, because it is limited to the anus and so doesn't present with the typical systemic symptoms. Paulspain's posts provide great information about peri-anal crohns and setons. It does sound, though, like in your case crohns is pretty unlikely. I've heard (from friends and family) that diabetes can cause anal abscesses and fistulas. Maybe you can ask your doc about that?
I'm keeping my fingers crossed that there is no underlying condition - sometimes these things do happen and it's just a matter of bad luck. Good for you getting yourself to a good doctor! You've got a lot of spunk and you're very sensible, so you've definitely got what it takes to beat this! :D
