I keep having recurrences and I'm not sure what I can do to stop them. Hoping to get some advice. They all occur with whiplash type injuries mostly in transport (cars, buses, etc.) and the full host of symptoms accompanies them (prior to each incident I don't have any symptoms at all) and I am completely out of commission for months at a time. Movement up and down doesn't seem to cause any issues but rapid head movement back and forth creates problems (like if a car/bus breaks too quickly and I get jolted forward, for example).

Are there any types of things I can do to strengthen my neck to prevent this from happening? Other things?
