Hi Im A 21 Year Old Female And As Of

Hi im a 21 year old female and as of this morning i started having bad stomach cramps (mainly upper and chest area) also my entire back. I have blood in urine and the only release i can find is curling up into a ball with a heating pad. I started throwing up but in my opinion it was because of the severity of the pain. Ive never had such terrible pain. Im sure its the stomach flue but the blood in the urine and upper ab/chest pain just keep getting worse
