Re: neck pain and numbness....
I can't diagnose you, but I have those symptoms, including that I get numbness in my right cheek now & then. I get severe pain in a local area of my neck, and it usually spreads to my left shoulder with terrible spasms. I've had my complete arms & hands go numb as well. I noticed that my arms go totally numb (usually) when I wake up from sleeping and my head was tilted back. I've gotten and still do get pain that runs down my arms and severe nerve pain in my middle three fingers on both hands that comes & goes.
When my neck pains all started, I was in the midst of a severe lumbar spine condition (which was worse) and my rheum back then told me one thing at a time and insinuated that my neck/shoulder problems were due to fibro. So, I was never sent by him to get any imaging done on my neck. My upper back problems just slowly got worse over the past several years. Several months ago, I saw a new PM. Since my last MRI's were from 07, he sent me for all new MRI's of both my lumbar & cervical spine. Then I found out that I have a large disc herniation in one neck level and stenosis in others. My spine in my neck has actually straightened out over time due to my severe spasms (that my rheum said was fibro). Now I have spinal cord compression with right hand weakness. I just saw a neurosurgeon who recommended surgery and he was the one that told me my right hand is weak. Unfortunately, I just cannot have surgery, not anytime soon due to financial reasons. The neuro told me, though, that I could end up with serious problems if I ever get into a car accident due to the disc already being pushed into my cord. UGHH. I'm not saying you definitely have something similar, but it sure sounds like it. Mine is caused by spinal arthritis (osteoarthritis as far as I know, not RA) I had forgotten to ask him if my facial numbness could be caused by anything on my MRI report, though. I did just read today that complex migraines can actually cause facial numbness also...and I do get migraines, mostly just with auras. Occassionally I get the headache. I do take a few meds, which usually help a lot, but sometimes it just flares up very badly. I do know that cervical arthritis can cause headaches as well, just not migraines. They usually go up the back of the head and sometimes around the sides and/or behind the eyes.
So, I do know how you feel as I've had similiar experiences. Fyi....I also have lumbar spine issues. All the nerves that run off the spine at each vertebral level actually go out and down, so issues in the lumbar spine cannot be causing your cervical spine issues. I just don't know why so many docs, if they know you already have lumbar problems, why they think you can't have cervical problems also. I don't know, maybe it has something to do with the insurance companies, I wouldn't doubt it.
I think you should see another doc and get another opinion if you can.
