Holding urine often can lead to cystitis, so you should go to the hospital to see it.

Is it because there is not much urine in the bladder (is the penis hard (erect) causing the urge to urinate?) If it's cold and you don't have enough blankets, you will still have the urge to urinate even if you don't drink much water. According to what you said, there should always be a urge to urinate every morning.

It doesn't matter if you drank plenty of water or urinated the night before. The body's metabolism has countless chemical reactions every day, and the chemical reaction will produce water in ten. So there's nothing unusual about what you're talking about.

Do you wake up with the same discomfort every day? How old are you? Have you ever seen an orthopedic department? There are many possibilities for low back pain. For example, if you have ejaculated frequently recently, your lumbar vertebrae have growths.
