Once in July while flying & just now in my home I held my urine longer than normal, then when I went to release I had excruciating lower left back pain when urinating. The first time it was so bad it sent me to my knees, which was difficult since i was in an airplane laboratory. That first time I prayed for my death instead of healing it was so bad. it may have lasted 5 minutes & then continued a while longer a mild discomfort The next time was just a few minutes ago it was not as bad. What is wrong with me? Whom do I see for a repair? The email address provide is mine since 1998 and is legitimate so please put forth the effort to respond, Thank you, Male 42 years old with possible kidney issue
