No idea what caused the obstruction. No inflamation at all. The narrowing at the surgery site was minor - he did a dilation to make me feel "more comfortable". Now, unfortunately, I have fever, chills, fatigue, and headache. I've been switched to a liquid diet for today and it's "wait and see". He thinks the dilation "stressed my system". Hey, wasn't it supposed to make me more comfortable?
Why a trial drug? Because he's head of research for his group.
