You didnt mention any blood test results (e.g. liver function test).Also, did the imaging study not reveal anything in your GI tract?Either way, yes you should undergo a colonoscopy as soon as possible. The results of the colonoscopy will inform further management decisions.If you feel like fainting, or experience any symptoms that you consider to be drastic, go to the ER.Best wishes.
Age: 30sSex: MaleHeight : 5Ft 8inWeight: 180Race: LatinoDuration of complaint: 5 months+Location: Texas, US. Abdominal pain, blood in stool.Medical Issue: Had recurring blood in stool that increased in intensity and frequency. Saw doctor and prescribed Cipro after which frequency of bowel movements and amount of blood increased. Given prednisone which seemed to increase amount of blood in stool. Had CT scan of abdomen which revealed hepatic mass lesions. Primary care doctor advised and arranged for admission to emergency room for an MRI of the abdomen. ER doctor however reviewed scans from CT and believed they were cysts and wouldn't proceed with MRI. ER doctor emphasized need for colonoscopy first which I have scheduled for 31st, but he worries that is too far away. For reference it took me 6 weeks to get the CT scan. I didn't get a referral/authorization for an MRI from my primary care doctor. ER doctor told me to return on Monday and that I may possibly be scheduled for colonoscopy through their hospital. How critical is all this? I'm worried as I now have to wait the weekend at minimum, but likely will have additional weeks of waiting for paperwork/insurance authorization/scheduling before I can get these procedures.
