Hi,

I have found the wrist bans to help alot, and they are inexpensive and simple.

After my concussion, I had a shadow over my right side of my vision. One of my Dr's is also a chiropractor and he showed me the nerve that was being pinched and that corrected my vision instantly.

Any time that comes back I know that an adjustment from my chiro is not far off.
I agree with Mark, going to someone who is knowledgable in this type of issue is important.
