On Tuesday, I Had A Ureteroscopy. The Surgeon Said He

On Tuesday, I had a ureteroscopy. The surgeon said he found no stone, that I must have passed it since my last scan in November. On Thursday morning, per discharge instructions, I removed my stent. That afternoon, I had pain in my lower back, near the kidney area. I called the surgeon's office and was told it was to be expected. Three aleve took care of the pain. Today, Friday, i returned to work. No pain, just tired. This evening, i began having pain again, in the same area. Again, 3 aleve has helped stop the pain. I am also still having urges to urinate. I am finished with my antibiotic. I am still taking, once daily, Tamsulosin. Is what I am experiencing normal, and if so, for how long might I expect to have pain?
