This afternoon my childhood friend and I were putting a pot call together for hi s son-in-law , I turned my flashlight on to get a look at the underside just to make sure that the glass sounding board was still in place. As I looked up under I lost Equilibrium and was grabbing for something to catch myself. L ast year this happened once but lately sitting up in the bed in the morning and laying down I get dizzy. I see the doc in the morning for my pre-op for knee replacement. I hope she can tel me what happening. Hate to think of not getting over this, driving, the bike, I'm a bit worried.
