For the past few days, when I urinate, it feels like there is a bit of urine stuck in my urethra, like right below the tip. Therefore, I do not feel much relief after urinating. What do you think could be wrong? Do you think I have kidney stones? Kidney stones are my greatest fear. I have had no other symptoms of that. In fact, other than that feeling that I just constantly have to urinate, I feel fine. No other problems at all. I am a 23 year old male. I would sure appreciate anything you can offer about this. I am starting to really worry.
