Had multiple blood clots in the lungs last year. Fine now thanks to the blood thinners I was on most of the year. While I had blood clots as well as after - now the next year, I m still having palpitations especially when I work out sometimes, do yard work etc... before the blood clots I never had palpitations except once in a while - just something normal we all get. They aren t bad now but very annoying and when it does happen especially when I work out or do some physical work I feel a nauseas afterwards. Had all kind of heart tests last year which all checked out just fine I m good to go and Pulmonologist doesn t seem concerned. What do you think it is?
