In a lot of pain. Read details. What should I do?

I have been doing martial arts for 10+ years and yesterday I was thrown a lot by a 200lb+ 6'5 guy and I am only 4'10. I landed safely but I am extremely sore in my thighs, triceps, back, and neck. I tried taking a warm bath and I tried some pain killers, but nothing has worked. I don't have a way to go out and buy something right now. What can I do to get rid lf the pain?
