I've been having urinary problem for a week now. The pain has been reduced but when I cannot use the washroom immediately there is a mild pain. I've been drinking 4-5litres of water and frequently used the washroom after almost 15-30 minutes interval. I'm suffering from severe lower back pain from last Saturday after performing some housework. The pain increases when I have to sit for long lectures in college. I don't know if I should go to a urologist or spinal doctor or gynaecologist.
