Chest pain that last from 30 seconds to 4 minutes depending on the activity, Walked into a store grabbed my item and walked back to car. The chest pain lasted 4-5 minutes. I had a stint put in last month, I have been wearing a heart monitor for about 6 days now, and I recently started medication. 81 mg baby aspirin, 80 mg, Lipitor 25 mg Bystolic, 50 mg plavix... The chest pain just started on Thursday again, but different pain than the symptoms I was feeling when I needed the stint put in. I noticed the pain comes in after I have eaten something then do something.
