When they take biopsies they just grab a chunk of flesh with a crocodile clip so its like creating ulcers if they grab a big part. You had a lot taken so I'd guess this is why its all sore. I would call your Dr though as I don't think it's normal to be in so much pain afterwards, mine did sting for a couple of weeks after though
Also during colonoscopy they can pump in gas to expand your intestines and allow the camera to move through, you might be having pain from some gas still in there,I don't have sensitive bowels but even I was yelling at the from the pain when they would pump in the gas, they had to give me a double whack of sedation and I still wasn't properly sedated, felt the whole thing
Thank you for your comments! I did speak with a nurse from my GI clinic and apparently some people can develop the symptoms I've listed after EGD biopsies. It usually happens when people are hyper-aware of their bodies, which I suppose I am. Also, I have severe IBS-C and GERD, so I guess it was normal that I experienced more pain. However, I would have thought that people here on the GERD forum would have experienced something similar; so, that did worry me a little. My GI doctor said that there's less than a zero percent chance of having a complication from EGD (such as developing a perforation).
