So, I lucked out, I think. My neurosurgeon took a look at the new MRI and said the symptoms shouldn’t be coming from the neck (he said if I had any new problems it looked like it should be occuring on the right side, which isn’t sympotomatic). He thought I might have a nerve issue somewhere in the left arm. Prescribed a round of oral steroids. Took about two weeks, but I’m now (again) pain and tingle free on the left side. Gotta say it pays to listen to your doctor…
Now if medical science had a permanent solution to my lumbar facet joint arthritis I’d be really happy!
