4 year strong pain after sex, bloated symptoms of uti/kidney infection. no abnormalities on tests+scans on bladderkidneys, uterus, urine? is endometrios?

See answer: 4 year hx of symptoms indicative of a chronic problem. Possibilities include: endometriosis, chronic pid, uterine abnormality, or very likely a chronic "pain syndrome" such as interstitial cystitis/painful bladder syndrome (urinary urgency, frequency, bladder discomfort) or chronic pelvic pain syndrome which can be a symptom of another disease, or it can be a condition in its own right.
