chest pains, fatigue

I have been experiencing chest pains since starting my new job a month ago. Today I was extremely fatigued from a very long day at work and came home to take a nap. I started having chest pains on my left side about an inch in from my left nipple. the pain seemed to coincide with my heartbeat. I also have frequent palps and was feeling a little dehydrated today. My job causes me to move fast (meat cutter/butcher) for extended periods of time, and usually by the end of the day i am having some degree of chest pain. when i do finally relax after work sometimes its hard for me to restore a normal breathing rhythm. I also frequently lift weights, and never have any chest pain when doing so. so i guess my question is, is it possible to have a heart condition that could produce symptoms from cardio style exercise and not weight/stress style exercise??

Hello and hope you are doing well.

Cardiac pain or chest pain can be felt as a tightness and worsens with activity or exercise. Any exercise that increases the cardiac strain or pumping capacity will produce chest pain due to inadequate blood supply. Since the pain occurs after work everyday, it could most probably be muscular pain. But when in doubt always best to have it checked. So please consult your primary care physician who may ask for an EKG or a treadmill test to rule out a cardiac cause for the pain

Hope this helped and do keep us posted.
