For the past week and a half, every night I have had a muscle type pain in my upper left side. The pain only occures when I am sleeping. The pain creeps into my left under arm and to the back side of my upper chest. Why is this happening, and what is going on?
Thank you for your help.
Hi Medically Interested,
I recommend you contact your physician to be evaluated and determine the cause of your chest pain.
