It could be a number of things. But I am not a doctor. My best advice would be to go and see one.
I need help I keep feeling like I need a wee and when I do go and wee it hurts and recently down there has been stinging even when I don't wee ?? Is this a water infection helppp
You definitely need to see a doctor.
Water infection? If you're talking about a urinary tract infection that's something only a doctor can diagnose not a bunch of strangers on the internet.
Talk to your mom! Not strangers. And go see a doctor please. ☺
You need a doctor. While waiting, in the meantime...eat some probiotoc yougart and drink some low sugar cranberry juice.
