Ray:   Get yourself to a Hospital Emergency Room right away. It may be nothing but it's always better to check it out.   I woke up with a slight discomfort accross my back about 3 am. It seemed to increase and I awoke my wife and we went to th EM. It was a clot that caused a massive heart attack. Though I lost about 30% of my heart it still functions and I am alive. I'll have to live with the constant tiredness but otherwise I'm OK.   My close friend died suddenly and when I spoke to his wife she described the exact same discomfort that I experienced except that her husband passed it off to arthritis (?) and went to his easy chair to relax awhile. There she found him in the AM, dead.   Noone cares if you're wrong - they don't get upset and there is no embarrassment. It may save your life though! Go directly to the Hospital!!!!   Thom
