Thanks to all. They sprung me at lunchtime - EKG, blood tests and stress test all showed no sign of a heart problem but, as I said to the guy this morning, the ultra-sound shows I do actually have a heart! The doctor this morning said that sometimes these things can happen even without any signs afterwards.

The pain last night was pretty severe - scared me enough to want to go to the ER. The staff there were all great - really nice people who made a very stressful night much easier.

I'm feeling quite washed out today and shall be taking it very easy for the rest of the day. I've got an appointment with my own primary care guy next Tuesday to talk about it and maybe to look at the possibility that it could be GI related.

Once again, thanks for the good wishes. I love you lot!
