Please, Please, Please Help.
Two weeks ago my mom woke up at night with pain. She was having intensely sharp severe pain in her chest. She had a lot of trouble breathing and can't move. While she feels cold to the touch she is sweating. We called the ambulance for her, but by the time the ambulance came -- she was recovering. We made her go anyway and the doctor didn't find anything wrong with her!
But it just happened AGAIN! Except this time my parents didn't call the ambulance because the last time we did our health insurance refused to cover it. Please help me -- Whats wrong with my mom?
