I am a 24 y/o m with fatigue, loss of balance, and intermittent tingling in both of my feet at the same time. I've had metabolic panels, cbc, thyroid tests, mri/mra of the head, ct of the head, eeg, transcranial ultrasound, multitude of hearing tests from the ENT doctor. So far, my head is clear, no lab results were conclusive, (meaning no diabetes, thyroid issues) and no problems with my inner ear. I was wondering if anyone out there has heard of any conditions that could cause these symptoms that involve the neck. This has been going on for about one year, and my neck has not felt quite right but I can't really say I'm having pain there, or that it's stiff. Any help would be appreciated!
