Hi irishbrat38:

I'm glad that you didn't hesistate to have him see a doctor, anytime there is pain relating to the chest it needs to be assessed. Pain can present itself in many ways. For example, you can actually be having problems with your appendix but your pain is located in your shoulder. A lot of the time, chest pain can be stemming from stomach problems. If on examination everything came back okay in regards to his heart, I would suggest you try the Zantac (ranitidine) for a little while to see if his symptoms resolve. If you don't see any improvement, call your physician back to discuss what further options there are.

Here is a link to Check Your Symptoms and more information on different causes of Chest Pain.

Take care,
