Hello, that sounds very frustrating. I'm sorry to hear about this ongoing situation. You've done the right things in terms of seeing caregivers. Normally, nurse practitioners can be very good but agree that at this point, you need to see the actual MD doctor. You've gotten results of things but no treatment. A GI doctor that is the same each time can follow your case and help you heal this situation. Did the remove the precancerous polyps, by the way? I would assume so but wanted to ask that. Having inflammation as this has come up now more than once is treatable. Back and stomach pain are classic symptoms of an inflamed bowel. Inflammatory bowel disease is actually called Irritable Bowel Syndrome or IBS. You've probably heard of that. Sometimes it is called IBD for disease instead of syndrome. IBD can cause issues of diarrhea but also issues of constipation. It can manifest in different symptoms for different people. https://www.mayoclinic.org/diseases-conditions/inflammatory-bowel-disease/symptoms-causes/syc-20353315 But they DO treat it. This link has the diagnostic testing done normally as well as treatment options. https://www.mayoclinic.org/diseases-conditions/inflammatory-bowel-disease/diagnosis-treatment/drc-20353320
Antiinflammatory medication is normally given. Immune system supressors and something called biologics as well. Antibiotics are often given and other supplemental things as needed. Nutritional advice is important to receive as well as making sure to try to reduce your stress.
Let me know what you think of this information.
