I have been to the ER twice, Hopspitalized once. I have taken 2 CT scans, an Ultra sound, IVP, Renal Scan, x-ray of the bladder, X-rays, and a scope of my stomach--all test were negative except for the scope which showed 4 ulcers in my stomach. The pain I have been suffering from (7 weeks to be exact) is on my right side lower back. I also have a stitch from the pain going along the side of my stomach and traces of urine in my blood. No one can seem to find out what is wrong other than to keep giving me Percocet for the pain. when I was being tested for the Renal scan, the pain was so bad after they injected me with lacix(?) that I needed to stop and was taken to the ER. No stones were shown and all results are "fine". can anyone tell me what I should be looking for??? The pain never goes away, just the intensity increases or decreases. Please help I am feeling hopeless.
