Yes I have experience the same problem. And I have found that I only get the pain when I release the dumbell/barbell really fast. Next time you're doing curls or whatever it may be that causes the pain, instead of Letting go of the bar quick, slowly release the bar and that is what helped for me.
After your workout is complete grab 2 30-50lb dumbells. Whichever suits you best. Lay down in the fly position at the bottom of the movement, and hold it for 45 seconds. do two sets of this to add shape, and hardness do your chest. Worked for me
