It started like yesterday, at first I would literally just pee, and I d be almost done, but it d BURN, and there wouldn t even be much pee. Today, the left side of my stomach started hurting. I let it go, but after a couple hours, it started throbbing. It feels slightly swollen. It hurts to move, but it s still a little tolerable. I don t think I ll be able to sleep. Also, I m a teenager, if that helps.
