I was working on my yard today doing heavy lifting and general gardening . About two hours into it I went though a dizzy spell which I tried to ameliorate by standing straight and lifting my head. That gesture made it worse as I began to lose strength in my rt leg and the vision in my left eye became blurry . My lags lust gave on me and I had to sit on the lawn. I had gone through episodes of this type of weakness for the past three weeks but never this bad. I recovered after 20 minutes.
