I think k I passed a kidney stone about four days ago.. There was an urge to urinate, but nothing came out. I pushed and felt a sharp God awful pain, and blood came out with the urine, but continued pouring out in a stream after the urine stopped. I lost a bit less than a pint I think, it was pure red blood, clotting on the toilet and where it hit the floor pudding as I tried to stop the bleeding with wads of toilet paper and pressure.. Bled over night but stopped the next day.. Still slight pain when urinating. I have made an appointment with my urologist on the tenth, but his nurse insisted I see my regular MD now,.. She couldn t, but told her nurse to direct me to the EL, i ll go in the morning, she said they d need a cat scan. I m 55 never had blockage issues, just this first time.. I have had a burning pain in my lower abdomen for around a year and a half, increasingly difficult to walk or stand for long,.. I disregarded it because I have had spine damage, compression fractures, and nerve compression on the left side, assumed it was that.. If this is a severe kidney stone issue.. Am I looking at surgery? And can kidney stones cause pain standing and walking?
