Every year between July and August, my mom suffers from a lot of pain in the urinary track and during the urinary infection tests nothing comes up. If a uric culture is performed then the test results show some infections. She has tried a lot of doctors and many medicines until one of the docs prescribed Distone. She went for it and after a Continuous dosage of 3 months this pain would stop and would again start exactly the next year at around July and August during which she again takes Distone for a period of 3 months or so. The pain stops after that and again it occurs the next year at almost the same time. This has been going on for 5 years now including this year. I am not sure what the correct diagnosis is or what exactly is happening. I request your assistance. Please help and guide me.
