Hello, I'm a 24 yr old male from Florida and I'm here because I'm a bit concerned. The past week i have been having pain in my chest, neck and arm. It was so bad one night that i went to the ER. They took a chest x-ray and did some blood work and assured me all was fine. On top of the pain i could feel my heart and it felt like it was speeding up or out of rhythm. I still have pain but i haven't quite felt it like i did that night. I went to a family doctor and he did not seem that concerned either but I can't help but feel something is wrong. I'm frustrated with the drs reaction and I'm a tad bit worried. I'm not one for doctors or going to the ER. If i decide to go then it is serious. I'm incredibly stubborn like that. I also get really tired after the pain is gone. I have been sleeping a lot more lately. My fiances mother is a nurse and she is even more concerned then I. Can anyone help shed some light on this for me?
