Untill you get into surgery, you should probably get a good anti-inflamatory like Celebrix or Arthrotec (though arthrotec can make you nautious). Some good painkillers would be Tylenol-3 with Codein, and even better would be Tramacet (or anything containing tramadol). Until you get some good prescription meds (I don't know why you don't already), pop about 600-800 mg ibeprophen (800 is kind of pushing it, even 600 is, but I do this all the time when I'm in too much pain and need it. You won't die of liver failure doing it a few times, I promise ) .
Also, make sure you frequently ice the injury points for 10 minutes, then follow up with a hot bath to relax the muscles. If muscle tension is a problem too, get yourself some Flexeril (a really powerful muscle relaxant, but it can make you feel sedated and kind of drunk).
And if all else fails, your doctor may be willing to temporarily give you some meds with morphine in them, such as Oxycodone, Oxycontin, Vicodin, and of course Vicodin's little brother Tramacet.

Best of luck to you LIP
