Your posting is certainly ME personified. I have had a shortness of breath, some small spells of dizziness all of which I put down as good old PD. Well 2 weeks ago I flew to Buffalo for my Mother-in-laws funeral and that evening as I was getting out of the car I felt a rush go to my head and the next thing I knew I had cracked my head on the pavement and that woke me up. The paramedics took me to the hospital and in the ER I did the same thing. I am now the proud owner of a pacemaker. The electronics of my heart were haywire but I blamed the symptoms on PD. Actually, who really knows what goes on in the body, no two people are alike, they say. So pay close attention to what is going on within yourself and ask questions now. So happy I am still here to reap the wonders of this great family Elizabeth 68/2
