[it seems like the more I do with my hand, he more intense my neck pain gets.]

How did you happen acquire RSD?
Have you done repetitive work in the past?
Any hand, arm, neck , shoulder injury? Whiplash?

We have members with RSD that also had Thoracic outlet syndrome (TOS).
TOS is sometimes caused by long term repetitive uses & desk work type postures. There are also many other causes of TOS.
But often with long term TOS, RSD will develop.

If TOS might apply we have a forum with more info-
