Anal Fistula

I have developed what I think to be a fistula. I think it was caused by an enema tip that I inserted too far into my anus around a month ago. I noticed blood on the tip and thought to myself uh-oh. Anyway, It's uncomfortable to sit and it feels like there is a bump inside my left lower cheek that feels pressure when I touch it. It drains sometimes with a clear liquid coming out, mostly when I'm nervous for some reason. My anus is itchy, but it does not hurt to have a bowl movement and there is no blood. It feels as if gas leaks out of my anus and my anus feels uncontrollable, like it tightens up very tight after I attempt to pass gas. My lower abdomen also has a sharp pain when I stretch in the morning.

My personality has changed recently from being very outgoing and social to being introvert and anxious. A couple months ago I developed a body odor that comes out when I get anxious or nervous. This has caused a cycle that whenever I see people I produce this odor. I do not know if it is related to the fistula or not. Like I said, I believe the fistula was caused by the enema tip, but possibly also by stress of this condition. If someone could provide me with a remedy I'd be greatly appreciative. Please ask if you have any further questions.

Thank you so much,
Daniel
