Both answers below are correct. The question your indirectly wanting to ask is "tell me it's not a heart attack". This can be hard enough to do in person with the luxury of asking the details of the symptoms, this of course can't be done with the amount of information we have and we would need more than an online a valuation of course. People can go to the emergency room and sometimes have their heart attacks over look so much more and occur in the setting. But of course heart attack isn't the only possibility and it's not the only concern so definitely get from emergency room a valuation and technically if we were in the office and the patient were in front of us we might have to tell them that we have to call an ambulance even if we're not sure . I wish you and your mother well
