Hi, I'm a bit worried about my mum. She's been having a lot of chest pains and feeling a recurring pain in her left arm, she is also having a bit of trouble breathing at times. Sometimes she feels tired even though she hasn't been doing much and has had enough sleep. I'm not sure what it is, as I know my mum has always had a weak heart. Could these symptoms possibly be signs of heart disease/heart attack? If you have any suggestions, ideas or advice - please tell me as it would be very much appreciated!
