i have bad pain in my left chest for 2 days now. The pain is costant and intense, and very sore, very painful when I turn in bed, get up, lift my left arm , take a deep breath. The pain is deep down in the in my left chest( feels like I had a heavy load on my body and now its bruised and sore) Last month I got this pain again before my period and it lasted about 2 weeks.
