One or both kidneys may be enlarged and painful, and doctors may find tenderness in the small of the back on the affected side. Sometimes the muscles of the abdomen are tightly contracted. Irritation from the infection or the passing of a kidney stone (if one is present) can cause spasms of the ureters. If the ureters go into spasms, people may experience episodes of intense pain (renal colic).
NFPA 10 Standard for Portable Fire Extinguishers states that units weighing 40 lbs. or less be installed such that the top of the unit is not more than five feet above the floor. For units weighing more than 40 pounds, the top of the unit should be no more than 3.5 feet above the floor.
