I m 58, a diabetic and on many meds. I ve been at a home and garden show today..walking for about 3 hours straight...we went to dinner at Red Lobster, then walked it off at Target..my problem is that my resting heart rate is 119, right now...the center of my chest feels a bit tight, like when I need my mid back adjusted..my partner did adjust it a bit, but my heart rate hasn t lowered. I took my evening meds at about 9, including a baby aspirin, so I m surprised that this is happening. Should I get to the ER? YYYY@YYYY
