Brief Answer:
rectocoele or entercoele

Detailed Answer:
Hi,
Although there can be many causes of chronic pelvic pain, with your classic symptoms,it goes more in favour of rectocoele/enterocoele. With rectocoele you may notice.
you may notice:

A soft bulge of tissue in your vagina that may or may not protrude through the vaginal opening
Difficulty having a bowel movement with the need to press your fingers on the bulge in your vagina to help push stool out during a bowel movement ("splinting")
Sensation of rectal pressure or fullness
A feeling that the rectum has not completely emptied after a bowel movement
Sexual concerns, such as feeling embarrassed or sensing looseness in the tone of your vaginal tissue
Evaluation in your case would include a gastrointestinal evaluation, including a barium enema or colonoscopy, is recommended to eliminate colorectal malignancy from the differential diagnosis. Pelvic floor fluoroscopy may be useful for patients with pelvic organ prolapse and severe defecatory dysfunction. Dynamic magnetic resonance imaging provides a similar evaluation.
Prophylactic measures for preventing rectocele include diagnosis and treatment of chronic respiratory and metabolic disorders, correction of constipation, and intra-abdominal disorders that may cause chronic increases in intra-abdominal pressure.

You need to know about the preventive effects of weight control, proper nutrition, smoking cessation, and avoidance of strenuous occupational and recreational stresses that could damage the pelvic support system. Teach and encourage women to perform pelvic muscle exercises as a method of strengthening their pelvic diaphragm and as prophylaxis against the development of rectocele.
If symptoms are truly severe, then surgery via posterior colporaphy is an option.
Please note the diagnosis was made based on your symptoms. Other causes of pelvic pain in your age group includes benign or malignant tumors, interstitial cystitis, pelvic adhesions, or vulvodynia. Nongynecologic conditions, such as colorectal tumors, colitis, irritable bowel syndrome, and diverticular disease, may also be causes of pelvic pain. Thank you
