update: last week i smoke a boul, the pain became so bad, i went to the er. my arm was swollen, numb, and i couldnt move it at all. then today i went to my doctor and he know thinks its a pinched nerve in my neck. i did not tell him about the marijuana part, for varies reasions.. but does anyone know anything about this sort of situation? i have not smoked since then, and it is killing me.. i have a PT appiontment tommorrow, and next week a spine doctor appiontment. any help/suggestion or advice would be apprecated.. thanks
