Hello,
I can relate to spine issues and cramping. I had a L4/5 Laminectomy /fusion and a C4-7 ACDF. My neck is OK, but my back still hurts badly after many years.
Before the surgery I went to a pain doc who gave me too many spinal injections. That or the surgery caused Arachnoiditis! Look it up! It's not as rare as they claim. Mine comes and goes but spasms are daily. PLEASE beware of this before going for epidurals or any spinal injections!!! Best of luck. Be safe.
