Hi There
Reduced joint spaces, Wikipedia reference-linkscoliosis and spine fusion cause pain and shock like sensations radiating down from neck to arm/chest/Back/Fingers...
also with the condition you are suffering from might be compressing your blood vessels causing dizziness. Do you have any vision disturbances ?
avoid overhead activities, use a soft cervical collar-sponge and maintain a pain diary..
use it well to pin down the times- activities that increases your pain.. AVOID THEM AT ALL COSTS..

Ultrasound and Tens Should give you relief..
God Bless
