Chest pain!!

Of course right after I left this afternoon, Matt texted to tell me his chest pain is getting worse and he is going in for an Xray.  He said the pain in his chest hurts to breath - like pneumonia.  I am waiting for a sitter to get back in there to see what is going on.  Earlier in the day we were self-diagnosing him with me on the computer looking up what could cause it.  GERD was one of them, as was Angina.....
I'm hoping this is simple and he will be alleviated from the pain. 
Thank you for your support and well wishes!!!
