yea this happened to me about a year ago. cuz i use to sneeze so violently that everytime id get a bloody nose and everyone would laugh at me n shit. but anyways, i was layin in bed on my back and sneezed hella hard and pulled a muscle in my lower back...
but to this day, every time i cough i still get this pain where i pulled the muscle, this makin it hard to smoke bud cuz i cough just about every hit i take. shit fuckin drops me to my knees lol no joke.
