I have occasional sharp pressure/pain in the center of my chest accompanied by a pop when I bend over or lean back, it comes and goes but I believe it is caused by working out/sleeping wrong. Usually worse in morning or while I sleep. It is not my heart or indigestion. Definitely musculoskeletal. Please do not tell me costrochondritis. What else could this be? Could my ribs be rubbing together
Thanks for your question on Chat Doctor. I can understand your concern. Since your pain is associated with movements, and you are having bad postures in sleep, possibility of pulled muscle is more. No need to worry about rubbing of ribs. Do following things, you will definitely improve. 1. Avoid heavyweight lifting and strenuous exercise. 2. Avoid movements causing pain. 3. Avoid bad postures in sleep. 4. Start painkiller and muscle relaxant Chat Doctor.  5. Apply warm water pad on affected areas. Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
