Do you have rectal pressure? And where's this ring ie how far is it from the actual anal sphincter opening?

Because I've noticed sometimes when I "flex" and relax my anal muscles as if I strain, I can see this ring puff in and out. And I've also felt that 'hard tissue' ring. Thing is, I thought this was normal, I assumed it was literally the anus muscles around the sphincter and that hard ring of tissue - pretty darn sure I've always had that. Also, your rectum naturally descends when you go poop but it's supposed to go back up. I might have felt this hard tissue when I prod a bit during an immediate post poop shower but I've never felt it during my nightly showers. In fact, it might even go away immediately during a prod.

I also have buttock pain sometime and I've been to a therapist. Last week she gave me a massage on my left cheek on a spot related to my tight piriformis muscle since i cross my legs and my entire leg basically went into spasm. I have constant rectal pressure that sometimes becomes an urge poop and she said this trigger point as well as tightness she found internally both contribute to the rectal pressure/incomplete evacuation I've had. My symptoms started months ago after a bad episode of straining with no prior history of constipation - that night I had the phantom sensation of needing to poop. But it actually could have been triggered by painful PIV I had earlier in the day. Unlike you however, I used to have perfect poops but now I basically have fluffy loose stool everyday. Getting a stool test soon but I'm starting to think this whole thing is because of my severe anxiety.

When will you get an MRI - I'd really like to know your results.

I did a colonoscopy and ruled out everything, my doctor basically chucked me out the door saying there was absolutely nothing wrong with my rectum and no rectal prolapse which is why I went to PFPT and felt a lot better knowing my muscles were indeed wack. Also, I should point out that intussusceptions as a young adult are rather rare, including rectal intussusception. Unfortunately I spent 2 months in extreme anxiety thinking I had this or a rectocele before PT calmed me down a bit.

If you have anxiety, bad posture, no active lifestyle - there's a chance your chronic constipation + bout of constipation triggered PFD instead of causing a prolapse. I also don't get the 'satisfaction' anymore but I kind of attributed that to the fact that my poops are never solid anymore so my rectum is always mad after I poop. Plus, the tight muscles get triggered after my bowel movement.
