Three days ago I did my first chest workout since around the start of the year. Today, I am experiencing extreme pain from shoulder to shoulder across my chest as far down as my sternum. It is at the point where if I try to lift my arms away from my body more than about 45 degrees, shrug, lean over or even walk down stairs, it feels like my chest is going to tear down the middle.
I want to try and stretch it out a little, but the pain I get when I try is that strong that I am actually concerned about tearing something or causing some other type of similar injury.
I am not sure whether I can safely ignore what the pain is leading me to believe and do some stretches / use my normal range of motion where I can endure, or whether I am actually risking serious damage to the affected muscles if I try to use them as I normally would.
