Have a look at this question: 

http://bicycles.stackexchange.com/questions/967/what-do-you-do-to-heal-yourself-more-quickly-after-a-crash

This question has problems of its own, but the community should decide if we should give medical advice or not. This has obvious legal implications. Obviously, we need to tell people to see a doctor! (The poster here already has.) 

Please, if you agree with someone's opinion, vote it up (or down). Thanks!
