My son passed out on Monday morning and was taken to ER. he has pain in his shoulder and chest,also numbness in fingers -this is on his left side. ER did all kinds of tests, and say it is not a heart attack and don t believe it is his heart. Now today, he tried to return to work, and passed out on the job. says he fills exhausted, very tired - he has been under ALOT of stress. ER just told him he should go to a cardiologist specialist - if they did not think it was his heart, why would they send him to cardiologist specialist - also, my son does not have insurance and he felt they were just not going to go into real detail because of that - can anyone help me?
