Two weeks ago, my I took my husband to the emergency room because he had very intense pain on his upper left side. The doc diagnosed it as kidney stones, gave him some pain medicine, and sent us on our way, with the instructions that if the pain didn't lessen in two days, to come back. Well, two days later we were back. To this point, he has had x-rays, blood tests and an ivp. The urine test did show some blood in his urine, but his urine tests have always shown blood in the urine. The blood tests ruled out pancriatitis; the ivp ruled out kidney stones. We go back to the urologist on monday, to see what the next step is, but i'm worried about what could possibly be causing this and am looking for some possible explanations. The pain is not always severe, but is mostly always present.

About five years ago, he had almost identical symptoms and had basically the same tests ran, with the addition of having scopes used. The doctors did not find anything wrong at that point and eventually the pain ceased.

Anyone have any ideas on this?
