9 years ago i became severely bulimic. before i figured out the easiest methods of purging i used to force myself so hard that id pop blood vessels in my eyes and id wake up the next day with a lot of neck and upper back pain. a few years later after i stopped my bulimic behavior i started having chronic neck pain. i found out i have 2 bulging disks in my neck. ive never been in a car accident and the only time i can ever remember having neck pain (not just sore or tight muscles) was after a hard spell of purging. today i still suffer with the pain if i do not keep up with stretching. the few doctors i have seen say the injury cant be from vomiting but i really dont know any other cause. is there a chance that severe purging could have caused this?
