Help please

Mixed connective tissue, raynauds, ibd, tried all types meds,gluten,dairy wheat and pulse free not constipated nor runs, but urgency for loo asap or I'd have a problem. Persistent left sided pain, same spot ever 5-10 days lasting 2-3 day swollen tummy, very tender to touch leaves me exhausted off food. Constantly ask gp for help, awaiting urgent ct it's up to year 😪 also lower bowel camera urgent not even taking app, fed up. Had camera 7 years ago it showed interior fistula wondering could it be diverticulitis, crohns, ulcerative colitis anyone throw me a life line please
