I received 2 bilateral suboccipital nerve blocks 10 months ago.  Although they seemed to help for a couple weeks, it appeared I would need to continue monthly injections.  My insurance wouldn't cover the costs so we didn't do anymore.  About 4-5 months later, I started noticing what appears to be muscle atrophy in the suboccipital area on both sides.  As of today, there is a large "hole" there which I can only attribute to severe atrophy.  I get more pain and spasms in that area than I EVER had. I am a Physical Therapist and have seen muscle wasting in people after steroid injections in their extremities but I don't know anyone else (personally) who had these nerve blocks.  Has anyone else noticed this or something similar? Is there a way to reverse it?
