well i am 15 and i am constantly needing to pee like every 10 minutes this has been going on for months now it is so annoying, i have had a u.t.i when i was about 8 that went with some medicine from the doctors. I went to the doctors about this and he said there was no infection or anything this was about 3 months ago. I am worried as i have read this could be to do with cancer, diabetes and can lead to infertility.
Constantly thirsty as well? Go and see a doctor. If it is something serious then the sooner you get diagnosed the better. Please don't put it off.
no one can diagnose you here. if its burning when u pee and u have lower abdo pain, or blood in urine, it might just be a uti but to be honest only a doctor can do the job and treat you, it's been going on long enough.
