top of the breast severe pain goes near the left arm.
Hi Mary - This doesn't sound at all like a breast cancer symptom. But anytime you're in severe pain, you need to find out what's causing it. Have you had any heart issues? Seeing as it's on the left side, and spreads into your arm... Perhaps you should get in to see a doctor ASAP to ascertain this isn't a heart issue. Less seriously, it could be a muscle spasm, or a pinched nerve, both of which can be intensely painful. I hope you get some relief soon! - PJH
