I have a very strange question. I have stenosis in my neck at C 6 - C 8. In addition to pain shooting sown my arm into my thumb, I am now experiencing a strange fizzing sound that seems to start where my neck hurts, and continues into my head. I have migraines and the worse my neck gets, the worse the headaches become but the fizzing is new, happens ramdomly and only for a few seconds, then it's gone. Is this something I should be concerned about ?
