Thanks for reading my post. However CRPS has been diagnosed by Dr. Michael Moskowitz.

I think I have an entrapped nerve on my neck from bending my head back at the shampoo bowl. The burning of the dye had nothing to do with it, perhaps. A cervical MRI cannot show the octipital nerve. I wish it was just an allergic reaction but I never really had any redness and I never had any swelling.
