For many years I notice that when I stretch after sitting for long periods of time, my heart beats very fast and hard. It is NOT painful, but it does cause a pounding sensation in the back of my head I presume at the top of my spine.
I recently had a stress test and though overweight, my heart is strong. I am 5 foot 11, and weigh 248. (down from 270 last year).
I stretch and when I relax my heart beats harder and faster and I get a little bit dizzy.
Just for about 20 seconds or so, then it goes back to normal. It has been this way for years.
I do have a little arthritis in my spine and degenerative disc disease (both only in the last year). I walk daily for an hour fast enough to sweat but not get out of breath and I have no other tachycardia except when I stretch...
Is that normal or should i be concerned?
