My mother is having some pain above her heart. It's right under her left collarbone a little. She has shorten of breathe. She had pain in the left side of her arm. Is this a sense of a heart attack? Maybe asthma attack? I also know CPR for emergency cases only. My mom and I don't know why this is happening. This just started yesterday.

What did the doctor say when you took her to the ER? Chest pain is considered a medical emergency.
