Has anyone had Cervical/Thoracic Facet Joint Injections

Hello,

I have been diagnosed with Cervical Facet Osteoarthritis in my C7-T1 and T1-T2. I had a fusion almost a year ago, but it did no good as it seems I was misdiagnosed. My Orthopedic doctor recommended me to try a Rhizotomy...but doctor that would perform it said they do Facet injections first. I've had epidural injections and trigger point injections, and am wondering if these can help me? Are they long lasting or temporary? How will I feel after? I appreciate any advice/info.

Thank you so much.
