Hello~It could be muscular related, but in all honesty, I really think you should see your GP or even go to the ER, sometimes
women can have
heart attacks without the symptoms that
men have, they are called "Silent Heart Attacks" I don't want to scare you, but really, as I said, you should see your GP or even the ER, when it comes to chest pains associated with back pain, prompt action should be taken.
