Hello, for the past few weeks my chest has been feeling tight with the occasional sharp pain, mainly when I am either sitting or laying down. When I stand up and stretch to relieve the irritation, my sternum pops and my chest feels great. This occurs 2 to 3 times a day, mainly when I wake up and driving or sitting at work. The pain is not agonizing, but more of a annoying feelings. Any suggestions? Is it possibly I need to go to a chiropractor.
