I suffer from
frequent urination between 2am and 6 in the
morning. This happens every half hour, lots of urine, no burning, no pain.I have had blood tests, cystoscopy and an IVP done, all came back negative. I don;t drink a lot since i never get thirsty, a cup of tea in the morning and a glass of water for my blood pressure tablets. I'm not swollen but 2yrs ago i had a back op for a pinched nerve, could this be the cause? Please help!
