Good news, I think. They did EKG and ran a bunch of blood tests, took Xray. Everything negative. They scheduled me for a stress test.
However, I'm convinced it was reaction to the antibiotics I was taking for the staph infection.
When I think back, the problems started about the time I started taking them, and around 2 hours after each dose I would have a tightening of the chest and my blood pressure would go way up.
Needless to say, they changed my antibiotics.
Evidently the nitro tabs I had were no longer good. They expired two years ago and I had never taken one until this came up.
Thank you for your support!
