Oh, goshes, since the pain is in the area of the now missing gall bladder maybe adhesions for the GB surgery causing the pain, maybe even some constriction of the small bowel in that area??
For me, a blockage caused NAUSEA, pain, and more NAUSEA, then vomiting, probably fever altho I never took my own temp and by the time the partial blockage became a full blockage I was so sick, nauseous and in pain who knows what my temp was by the time I got to ER?? I sure didn't and, frankly, didn't much care. By that time the vomit tasted and smelled like feces. Before that ER visit tho, before the blockage became a full blockage it was just the pain, nausea and "normal" vomiting and the vomiting brought relief. Not total relief but tolerable pain and nausea.
Some people are like Slinkies... Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.
