Are there any alternative therapies for fecal body auras?

Hi there,
Surfer27 here. I just had a question to ask in, in regards to alternative therapies. I have this problem, with my bum and the thing is, it's letting off a bad feces type smell, that lingers with me no matter where I go. It's not me constantly passing gas, but when I do have gas, I do experience the sensation of it, when one has to fart. My problem is that, I am also noticing that when I let off a little flatuence, that it smells like the smell, that is emitting off my bum. I don't understand either the farting smell like my bo, or the feces type smelling bo either? What is happening with me? Can you offer me any advice or suggestions as to, what exactly is going on with me? I am concerned with this, because I firmly believe this is an internal problem, that is expressing itself outwards, through the pores of my skin, outside of my rectum area. Now just to let you know, I did have an unfortunate event, in which, about 2 yrs ago, I was anally raped!! What I am also concerned about with this, is if one, like myself is anally raped violently, then is it possible for feces to be lodged up into the colon area or leak into the bloodstream? Is that a possibility as to why, I am smelling a feces type smell emitting off my backside bum area? I did talk to my doctor about this and he doesn't believe me, which to say the least, is frustrating!!! I have also had a colonscopy done in which, the specialist said, that results came back as being normal, but is it also possible, that even with having this specific test done, that it could mean that my colon still needs to be flushed out? I am just wondering because, I am concerned!!!The colonscopy results also came back, as me not having a infection, no internal hemorrhoids, no anal fissure, and no anal fissure. I don't get this!! Could it be internal hemorrhoids causing this feces smell, or bacterial infection? Could it also be possible to assume, that maybe the reason my bum, is emitting this feces type smell is because I might, need to do a liver cleanse too? Please let me know what you think and what you would do. Thanks. Take care.
