I was in so much pain from the darn PEG! Like you, I was not expecting it at all. Most people dont seem to have a problem with PEG. It was the only time during treatment that I needed narcotics. Yes, I felt like I was kicked by a horse for about a week. It was too tight and they would not loosen it until a week went by. Actually what ended up working best for the pain was 800mg of ibuprofun, rather than the oxycodone. My nurse practitioner recommended I try it as some patients do better with it. It worked for me.
So for me the pain lasted little more than a week. My nurse also thought because I was thin to begin with, it was more painful for me than for others. You are on the small side as well, aren't you? Not sure why being small makes it more painful. Just take it easy for a few days, Hayley, and the pain will get better! Take care, Teresa
