I have a persistent variety of symptoms. Back pain, neck and low back have been MRI'd to no avail. Headaches accompanied by visual problems. Visual problems without headache...inability to move eyes to sides, light features in left eye that obscure vision. I also have numbness in my arms that has been attributed to carpal tunnel, occasional numbness in left front thigh, twitches in arms and legs and below left eye. My hands shake, blood pressure high (and medicated), generalized fatigue.
