Hello.. First time poster.
For the past few days to a week i have been having problems. When i urinate it all goes as normal and then when i am finishing it starts to feel uncomfortable, like i am trying to hold in urine but while it's coming out it also feels like there are mineral crystals or grains or something down my urinary tract. This provides a slightly painful feeling when i am finishing urinating.
It also feels like i do not empty my bladder fully and i have to go again.
After finishing it feels like i have a heavy feeling at the tip of my penis.
I am very worried because i have never had problems like this before.
I'm 16 if that helps if there are teen problems.
Also, sometimes, usually at night when i'm lay down i get a throb or painless ache in my testicle.
