Baseball player gets whiplash! What should he do?

Baseball whiplash

This video is an extreme example of whiplash, and it gets you thinking, what is the science about whiplash?

Mr. Villar's large neck muscles will go into spasm to protect him.  The two muscles which will spasm the most are the sternocleidomastoid and scalenes. 

When sternocleidomastoid spasms you suffer from headaches.  When scalenes spasm you suffer from arm tingling and numbness.  Mr. Villars will have both.  What should he do to relieve his pain? 

1)  get physical therapy for stretches for sternocleidomastoid and scalenes, and for myofascial release, and

2)  start working the "core" of the neck, the longus colli–(which is put out of commission by the whiplash) 

If he does both of these, his neck will probably fully recover!
