Sorry to hear of your problem, lilkay. I was told that by my first surgeon of 10 yrs😩 I did seek out other medical people, the head lecturer of the physio school diagnosed an obstruction and still that surgeon disagreed. I later learnt I was within my rights to seek a 2nd opinion.

Have you had a Bowel Transit Study done? It's an inexpensive, easy test which I feel she be done right at the beginning of ones troubles.
I didn't know of it, but was finally referred for one after 12 yrs of being on Colorectal surgeons books. It showed very clearly where a large obstruction was.
Surgeon gave me a diagnoses of Slow Transit and wanted to take all of my colon out! I almost went thru with it but gut feeling said NO and I asked for more investigation before having such a major op as that & possibly ending up the same or more problems. He didn't make much effort regarding more investigations.
I had been requesting a Colonoscopy via our public health system all this time but neither surgeons I saw would refer me 😫 stating I didn't fit the criteria - huh! I had every symptom of bowel cancer except from loosing weight.
With some financial help from my adult children I had a Colonoscopy done in the private sector. I too have a tortured colon & I watched on screen, the obstruction at my splenic flexure being blasted apart with compressed air. It was an unexpected feeling inside me and an astonishing sight which I will never forget but the Dr who performed the procedure denies it happened👎
He is covering the asses of the two surgeons who had failed to diagnose it.
Within a few days I started defecting almost as normally as I did 30 yrs ago.
I've had a lot of atrophy occur during this time - also 'not' noted in the report - but severe diverticulosis in my sigmoid is. I paid NZ$2,700 for the procedure and the Dr now refuses to provide me with a copy of said Colonoscopy.
I feel I can trust almost no one in the health sector now, so have sought the help of a Patient Advocate.
My hubby was killed 6 yrs ago and he was such a great support when it came to my ill health. I also have severe sero positive Rheumatoid & many other illnesses associated with it. It's very difficult having no one to support you.

But I digress. Request a Bowel Transit Study if you've not already had one.
Best of luck. 💞💞
