I have been feeling very lightheaded for the past few weeks, my vision sometimes goes severely blurry (and crossed eyes), and I am exhausted. My main concern is the crossed eyes, it comes and goes and do not know what would cause it, the last time was about Jan 11. my husband and I were crossing the street and I lost ALL of my vision, when he turned and looked at me my right eye was pointing left 90 degrees and amy right eye was pointing directly up. Can ANYONE help????
