Hi, needing some questions answered!!

Hi Tujam,
Surfer27 here. I just had a couple of personal questions to ask you. Umm, okay this is still hard to talk about, but here it goes. Okay, I was anally raped about 2 yrs ago. Eversince the event, my sphincter hole area never closed up fully on the outside. By this, I mean my external sphincter area. It always seems to be open and letting out constant gas. The other thing I found, was that, since the event, I have noticed that there is this fecal body smelling aura constantly around me, whereever I go and it's not wanting to leave!! I am also concerned because, I fear that when the event happened to me, that it pushed actual fecal matter up my colon area into the bloodstream! Is this possible for anyone to have that kind of a thing happen to them, after they are raped anally? I am just a little concerned, because I am wondering if that is why I am experiencing all of these top and bottom mentioned symptoms. I talked to my MD about the lack of external sphincter strength and he examined me and told me, to get a colonscopy done. I also mentioned to him about the feces type smell consistantly and he didn't believe me!! So my doctor referred me to a specialist, for a colonscopy. I had that test done and the results came back as being normal. There was no infection, no anal fissure, no internal hemorrhoids, nothing. How can that be? I then, had a meeting with my MD not too long ago and told him the same thing, that I was experiencing the same kind of problems and then, he told me, to do this Kegel Excerises to strengthen the pelvis floor muscles and the sphincter muscles. I have been doing this for the last 2 months everyday and haven't seen any improvement, in the decrease of these problems with my rectum/anal canal and my external sphincter. I am finding this very frustrating for me and was wanting to know, if you could help me out, by offering me some advice on this if you can? Where do I go from here, if I have done everything my MD has told me to do and yet, there is no improvement? Have you ever had this similar problem like mine, where you are constantly expelling gas, or have this feces type aura, that lingers with you, no matter where you go? If so, what have you personally done, to fix this, or relieve this symptoms? What have you tried? What has worked best for you? Can you suggest any ideas for me, as to, maybe what to specifically ask the doctor next, ex. seeing a proctologist? If you could get back to me on this, that'd be great!! Thanks. Take care.
