So before this happened i thought i had a yeast infection, because it was itchy and burned when i peed but now i have this bump that is way under the skin and hurts when i touch it since two days ago and i have these pains coming from my bladder almost like a subtle sharp pain and when i treated the yeast infection it didnt go away. i recently started having sex so i thought that , that might be why but now im worrying myself that it may be something more serious than i thought or even an sexually transmitted disease. pleaaaaasee help if anyone knows whats happening to me. By the way i am 17.
