I am afraid I have a rectocle but my PCP says no...is it commen to be not dx

Body: 

I have back ache, difficulty moving stools, and a feeling of pressure in my Bowels. I have had a colonoscopy and a physical exam of the rectum and vagina that were normal..The colonoscopy showed internal hemorrhoids. To be honest..although i am sure some of you will be aghast, I have had anal sex. (I now regret!!) Does anyone know if anal sex can cause a rectocle? How common is it to be not diagnosed.

just how common though we will never know. my rectocele went undiagnosed through 7 visits- 5 during 2 different pregnancies and 2 postpartum visits. This was with 4 different midwives oh and one obgyn who is a kick butt doctor- backing the midwives- I suspect he knew about it because he insisted on checking me for a fistula (which meant I had to deal with a rectal exam) but he never mentioned it to me. I was finally diagnosed when I had a midwife check my tear from birth and complained that it was not healing well- I was actually hanging my butt off my couch so I was sitting up and she noticed the bulge that way.
I believe that most women have prolapse. At least all the women I have talked to or given the link to the self exam document do- I have a friend who has all the classic symptoms of a cystocele- she feels the half pipe feeling along the anterior vaginal wall and has to pee right now or else- and when she went to the obgyn to check specifically for prolapse they told her she didn't have one- when according to her self exam she does. I think the position they put you in to check doesn't really show a prolapse well- and the fact that most annual vaginal exams just do a cervical swab, feel the ovaries, and rectum both lead to under-diagnosis. oh ya and the fact that the doctors see so many of them they must just think it a variation of normal.
You can check for yourself though with no problem- look in the articles section on the main page.
I am not aghast about the anal sex. and I kinda doubt it could cause a rectocele. I have no clue though-do you think the penetration was rough- did you notice pain etc?

Thank you so much for your reply. I welcome others. Thank you for pointing me in the right direction for the self exam. I did the exam and think it may be possible for level I but didn't see any signs of level II. It was hard to tell about level one, it did feel like a pillow but it really didn't move forward that much. A little perhaps. I also was dx with overactive bladder about 3 years ago (before the anal sex). However, my symptoms were not as they report them on TV or in most literature, rather I felt like a had a urinary tract infection constantly. detrol however has made me asymptomatic for 3 years until my colonoscopy. After the colonscopy (3 days ago) I came home and felt my old symptoms again. I was also bleeding vaginally despite being on the pill and it being over 1 week until my period was due. I called the GI doc and he didn't think it was related and wanted me to follow with my pcp. LUCKILY I have been taking Advil and the overactive bladder, urinary tract infection symptoms have subsided quite a bit. Just shows how close all of those organs are together. Im doing the fiber thing and stool softener think and I feel a bit better. I have also been wearing a back brace a work which seems to have helped me with may back pain. My back pain is worse on sitting, It is OK when walking. So I don't know what I have but it has been trying.
Thanks for listening.

I went through years of problems with my bowels, had exams, colonoscopy, sigmoidoscopy, etc. By the end of it all, the doctors had me thinking I was just some crazy lady with psychological problems. I finally went for a defacography (They put you on an x-ray potty with barium paste in your rectum) it was a rather embarrassing test, but at last I could see what was happening. The pocket where my stool was hiding was very clear. I can remember feeling very relieved that day. Just knowing that I wasn't crazy. The doctors have failed me in so many ways over the years. Looking back, this was inevitable. I went through 10 years of undiagnosed hypothyroidism (which causes constipation), then 10 years of being under-medicated for said condition (which causes more constipation); two vaginal deliveries (on my back); combined with heavy lifting (on a farm); and poor posture for 40 years. Of course I have a rectocele... who wouldn't! My advice to you... trust your instincts... not the doctors!
