cervical spine injections

I have a lot of neck arthritis and it doesn't play well with migraine. I also have probable cluster headache. The migraine flares up my neck, and my neck pain triggers the migraine. It has been suggested that I consider some treatment for the neck with injections and other wonderfully scary things. Does anyone have experience with these procedures? Did they help or cause things to be worse? I live in Oregon and would also value any recommendations as I am very anxious to try something like that without knowing I am seeing a trusted provider. (I don't know if giving names is allowed on this forum, if not please don't do so). Thanks!
