Hi Lex86 I am experiencing very similar symptoms as you are. I am also 34 years old/male and am otherwise a healthy person.

I just posted a thread in this forum that describes more of my symptoms that you can refer to if you'd like more background. I am also having a cervical MRI performed later this week and am anxious what the results will be. The common issue I have experienced the entire 9 months is the dull-achy left shoulder pain and no one has been able to tell me what this might be. I am considering asking the Neurologist for an MRI of the shoulder and/or a spinal tap which might provide additional clues.

I'm assuming by now you have had your Cervical MRI performed, how did that go for you? Take care and let me know if you have any questions or have made any progress.
