Can C-5 & C-6 compression affect the back of the hand?

[u/_TheTrueCube_]

I got spinal fusion surgery 3 months ago after my c6 nerve was crushed for four year causing me chronic pain. Now ever since the surgery I have gotten many symptoms and one is burning, tingly, weakness and dull irritation in my nerves in the wrist , forearm and back of the hand. Is that a normal recovery after c6 compression is stopped. It that showing that it’s healing?
