so i was smoking a blunt and a few bowls. then drunk like half of a highlife and then like an hour later we smoked some more. then i walked my bike to the busstop with a friend and i got the wierdest shoulder pain/twing thing in the back of my neck and upper shoulder. it was like painful and wouldn't go away. i felt like i needed to rip the skin off and fix it. idk. it freaked me out. anyone else get muscle spasms?
