I Ran Yesterday On My Treadmill. About A Hour Afterwards,

I ran yesterday on my treadmill. About a hour afterwards, I had this tight, dull pain in the middle of my chest. It was come and go. That evening I had two drinks and didn't notice it at all. I slept fine. As soon as I woke up this morning, the pain is back. It's worse when I sit down. I feel like it could just be a pulled/strain from running? I'm just concerned with the placement of the pain!
