My 8 yr old son has been complaining of his penis hurting. doesn't hurt when he urinates but does afterwards.what can it be?

Here are some ...: Despite not hurting at peeing, still need to confirm if he has UTI with urinalysis. Meanwhile, check if the foreskin is inflamed. But bringing him to see urologist timely is still most important. Before doing so, collect the information on the onset, degree, duration, interval, evolution, progress of all Sx over time for Doc to analyze + physicals + tests as needed so to deduce possible Dx for Rx.

See doctor: This could be a lot of things. Check out his penis, ask him to pion to you where it hurts. Location is impt, appearance is key. Does it get red, itchy, does it bubble up. Is he circumcised? Is the urine normal looking (clear, no crystals, no cloudiness).? Hard to tell unless he is examined and urine is tested. Good luck
