I have constant pain in every joint, from my head to my toes. I lose my balance all the time. I am very tired to the point I could fall asleep standing up. I've had restless leg syndrome all my life (sometimes a prelude to MS). An MRI was clear. But I haven't been able to walk very well since last week. My ankles and heels are very stiff and extremely painful. I can only hobble around. After 3 days of this I went to the hospital to see if I had somehow twisted my feet. They took x-rays, no damage, blood work, no inflamation, everything came back good. But I still can barely walk. My nuerologist said I have Firbomyalgia, but I didn't think it effect walking. I've not yet had a spinal tap. Could these symptoms really be MS, even with a clear MRI?
