A few months ago, I was stopped dead in my tracks (was leaving work, simply walking to my car)with this horrendous pain
under my left shoulder
balde. It was so bad, I could hardly breath, turn my head or walk to my car. It went away w/in a few days to a week. About a month after that, the same thing happened (was just standing on my front porch, went to go inside)but to the right side this time.. Again, that went away with in a few days..
