I've been experiencing this weird sensation where it feels like my urine is getting stuck in my urethra. My bladder thickness came out normal in tests, and I had a prevoid volume of 584ml and postvoid of 44ml. The prostate is supposed to be normal at 20.4 grams, but I have noticed there's less pressure when I try to pee in the morning. This has been going on for about 67 years, and even when I had it checked earlier, the doctor said everything seemed fine. He even applied pressure inside my anus, and some liquid came out of my penis, but tests showed no infection. I'm just confused about what's happening. Could you help me understand what might be causing this?
