IF and when you have another kidney stone the only med that worked for me was Toradol. It was amazing. The pain practically went away. I had severe kidney stones while I was on Topamax. I ended up hospitalized with a stone that got stuck and had to be retrieved out of the ureter. My right kidney started to fail because they did not know it was stuck. We thought we would wait for it to come out on it's own. After four days of waiting and no kidney stone, back to the hospital I went. They found out that my ureters were the size of a child the age of 8 or so. So, naturally, any stone, even small ones, have the likelihood of getting stuck. After that scare I no longer take Topamax, and no more stones.
For me Toradol was a wonder drug. It was the only thing that worked. I continued to have the severe pain that you describe due to the kidney spasms. It causes the same stabbing pain in your side and back, but up higher around the kidney. You have to be carefull with Toradol. It is not meant to be taken everyday.
Hope this helps.
