I too get the Numbness and tingling in my face, ear and eye. My eye spasms and goes funny so things get blurry like a migraine aura. I get hearing loss like a few of us get ....thinking of Astern. I get a ringing and then tingling and then sometimes loss of hearing all together. My emg's are normal and my MRI"s are normal.....so in my head I guess LOL..... not funny at all but as you said is it in my head well yeah it is. The cervical nerves as mentioned by Di are the main cause of our distress. Increased inflammation on a bad day can cause more compression and more pain and more irritation of the nerves that innervate your face and ears and eyes. These nerves are so close to the brachial plexus that is one reason why we have these issues. Check out this link.....
