Good advice. I am talking to the doc to up my appointments. One is a stress test. But, this has been an ongoing process. So far the therapist as well as the doc say I need to just build back up, with more walking. I doubt they would be happy if I told them about this, but when the doc calls me back I will let her know.Hombre, in February of 2008 I had a very similar experience changing a tire. About the only difference was mine was on a 30 degree day. I blew it off as to being a little out of shape and the cold air. Three days later I had a heart attack. Not trying to frighten you, but get checked soon, like today if you can.
