shoulder in agony

17 days before heading to Thailand, with the main goal of training, and I manage to bang up my shoulder. My right shoulder. i got swept during a rolling session at the gym yesterday afternoon and came down right on my shoulder. pain was accompanied by a snap-crackle-pop. stupidly, i kept rolling with it hurt (lightly, thankfully). i tried celebrex, aleve and scotch to dull the pain, but to no avail. last night, trying to sleep was brutal. i had to sleep on my back with a blanket holding up my arm. today, i went to the walk-in clinic at the university. the doctor totally flipped out at the slant of my shoulders!! she poked and proded and finally suggested that i have separated my shoulder. peachy. so i have to go get an x-ray, keep my right arm in a sling to keep the weight off the shoulder, and take pain killers. FUCK!!!!!! how much does this suck?? i am not a happy camper right now.
