Grace, are you taking meclizine (Antivert) for the dizziness?

Some doctors recommend not using it because when inner ear signals go wonkey (injury, or viruses), the brain needs to recalibrate and adjust to the new signals. If that cycle is blocked by a drug, this new learning does not take place or is highly delayed.

Also if you suspect neck issues, you might try using magnesium lotion to relax the neck muscles, and take some pressure off the nerves that way. Magnesium also works on the NMDA pain receptors, and also improves blood circulation to the strained tissue areas.

This is very inexpensive and works very well for relaxing tension in any muscle. Some stores have it on the shelf... WalMart and Walgreen's. It seems slow to enter local retail outlets though.
Just use a nickel's size dollop on your neck to loosen it up.
It works for feet and legs and back too. Try it on your insteps for your numb toes. (the skin is too thick on the bottoms of the feet, so don't apply it there). I will relax any leg tightness should you also have some strain in your back from your fall.

This simple solution, is really something everyone can benefit from at times. So do try it.
