Been in pain since yesterday but nothing is happening... I've tried walking and taking Tylenol but nothing helps... I don't know what else to do. If I go to the hospital all they are gonna do is keep me for an hour and if nothing happens they are just gonna send me home and I will have wasted gas for nothing... I feel so lost right now.. 😢
