I take 800mg of ibuprofen every 4 hours, its not doing Anything

Though I took my next to last pain killer and I am feeling a little better. I hope I can get to the doc soon, I'm down to my last pain killer, and maybe I could get a prednisone burst or something--by the second day I could feel a differnce last time (and only time lol) I had a prednisone burst. -shrug- Something, I'll try just about anything right now
Thanks bebop
