I had an upper endoscopy and colonoscopy yesterday morning. I had been having severe abdominal pain and constipation issues. Colonoscopy was normal; I have severe IBS-C. I've GERD for a long time and was diagnosed with eosinophilic esophagitis in 2009. My GI doctor took 5 biopsies in my duodenum to check for occult celiac disease. He also took 2 biopsies above my gastroesophageal junction and 2 from my mid-esophagus. Yesterday I wasn't able to eat anything, because whenever I tried to eat, my chest would get tight when the food was going down. Also, my back started hurting...it's very annoying and feels like someone is pinching inside. The back pain is on my left and is mostly mid-back, but some upper back pain too. I don't have a fever and I haven't coughed up blood. Has anyone else had this type of pain after EGD? Thank you.
