Hi Bill,
Welcome to NeuroTalk!
Congrats on the measures you have taken to help yourself.
As for the numbness in your head and spine, you may want to get an opinion as to the cause. Having more information about the cause will help you to determine what to do next, if anything.
Please ask your primary care physician to help you with the appropriate evaluation/referrals.
Also, please see related forums here. Please make yourself at home here.
To Our Healing,
DejaVu
