Is it ok for me to take one 5 mg oxycontin pill that was't prescribed to me, for my severe ear pain. i hit the 6 pill limit in 24 hours for ibuprofen and need something until i go to the drs tomorrow or would it b better to take 2 more ibuprofen?

I wouldn't: Given that possession of that pill, or evidence you took it, regardless of your situation could land you in jail I would avoid it. Placing a heating pad on the involved side of your head may give enough relief to get you through. If the doc decided your situation required that level of pain meds you could possess/use them with no risk.
