My own case, not your isues but to demonstrate that you should get another opinion or maybe several from different fields of medicine:
I complained of lower abdominal pain for at least about 2 years, starting when I was in a bad wreck. It wasn't horrible, so my PCP, gastroenterologist, and later my gyne all ignored. I was on antibiotics for chronic recurring sinus infections about once a month, needed and still not finished with surgeries related to the wreck. Gastro doc did lots of tests, upper and lower endoscopies. Was in the hospital last year for Dx of abscess from diverticulitis. Recently had the same symptoms as the abscess, went to hospital, same Dx of abscess. Drain tube started leaking stool through and around the tube, and still they waited before deciding I needed to be gutted like a herring. I transferred to another hospital, needed lap appendectomy which surgeon said had had the abscess a very long time. A week later the colon started leaking where it had been slightly attached, peritonitis, more surgery to remove that piece.
I had a similar problem with pain in legs and feet. 3 docs said nothing wrong. Podiatrist Dx pain coming from back. Pain doc gave spinal steroid shot which stopped the pain.
So even some very good docs didn't catch everything. I still respect all of them. Sometimes the symptoms just aren't quite right for a diagnosis.
