So it’s hard to explain but my chest feels weird kind of like strained? Without the straining. It doesn’t hurt, but it’s just an agony somewhat light aching feeling. I’m not sure where it came from because I didn’t notice until today after walking my neighbors dog. 

For extra note: my neighbor dog likes to pull and tug a lot. So I normally hold the leash around my wrist and my posture is slightly leaned back as she dragging/pulling me around.

Has anyone experienced this feeling in their chest and do you think me walking dog has anything to do with it?
