I am a healthy male 58, sudden onset of loss of equilibrium with walking, tend to lean to the right. unable to write as well with my right hand. Onset 2 weeks ago with new eyeglass prescription. today went in and rechecked and prescrip is right for my eyes. The problem is something else. No stroke s/s facial droop or sway to arms with standing and holding arms out. When I touch finger to nose the right hand touches just above the lip while left hand goes directly to tip of nose. I have no sit to stand dizzyness, it only occurs while ambulating.
