Thank you all for the replies. I ended up going to the ER. I had a cat scan, which showed a lot of inflammation and quite a few kidney stones, one 3mm stone in the left distal ureter, many in the pelvis. They were kind enough to give me Dilaudid without much of the "are you just here for drugs?" kind of reactions, and the doctor said he couldn't tell anymore without a colonoscopy, which I usually have in July, but he would like to have done as soon as possible. Unfortunately, my GI is overbooked today, so her nurse is getting all the info from the ER (which I also have), and my GI will make some decisions from there. Thank you all for your quick response....I know that we all hate having to make that dreaded trip to the ER!!
