I m a 54 yr old woman. I wanted to ask about heart attack symptoms for myself. Is there a blood test or will an EKG to tell if I may have had a heart attack? Two nights ago about 9:00 pm, I had a horrific pain in my upper back start in between my shoulder blades area that sent pain to both my arms then traveled up my neck into my jaw. I took an aspirin just in case. I had a RX of Nitro from Angina so I took one, it helped a ill bit but pain was still bad! So within 5 min, I took a 2nd one & the pain finally started to go away gradually, and then had a horrible headache! Since I felt better I chose to not go to an ER because we live in a small rural town & didn t think they had a Cardiologist here. I ve had family with heart prob & have had to transport to SLC, UT since there wasn t one here. Now I feel stupid! Had this happened to my husband or family I would have called 911 or took to ER myself! But when it s me I don t want to cause worry or inconvenience my family & convince myself it will go away! Should I be concerned it can happen again?
