Hi.. My name is Harold and I m 61.. I came to my studio about an hour ago and had to come up short flight of stairs while carrying equipment.. I was not winded and my heart rate was in the 80 s.. About 20 mins later I went downstairs to the bathroom.. When I finished I came back upstairs only this time I felt my heart beating faster.. I took my heart rate and it was 146.. Well, being that I suffer from anxiety I became concern.. I figured it was the restrroom along with the food I may have eaten prior to arriving.. Well, I ve been sitting for approx 15 mins and my heart rate is still in the low 100 s and it s making me anxious.. Could this be the anxiety? I have no other associated pain except a little strain in the upper right side of my back and that s from carrying all that equipment.. I hope..
