I had that but I had a prolapsed bladder. It fell through the vaginal wall. I had a hysterectomy and the bladder repair fixed at the same time. Don't have any pain now.

Yes. I've had ultrasounds done and nothing was found. For me it feels like swelling.

It could be from the fibroid too. The reason I had the hysterectomy my uterus and ovaries were filled inside and out with collagen fibroids. I felt like I was pregnant again and felt constipated all the time. Hope this helps.

I have irritable bowel syndrome. Maybe it's from that. I have had colonoscopy. I have had biopsy of my uterus. All normal.. I do have a fibroid tumor.

Not sure what it is. Did they check your colon, intestines or bowels? It might be inflammation that comes and goes too.
