Chest Pain with Left Shoulder and elbow pit pain

I feel like I am just a paranoid kid asking this, as I am only a 33 year old male, but here it goes.  For the second time within a one week period I am experiencing moderate to medium chest pain.  This pain is also felt at the left shoulder blade and down into my elbow pit (for lack of a better explanation of that area).  Today this has lasted for about 4 hours, with the pain being on and off, and has yet to end.  Last Thursday, I had a very similar experience, but the pain only lasted about 10 min.  If anyone has any ideas as to what this may be, please let me know.

Thanks!

First of all, age doesn't matter, even small children sometimes have these type of problems.

Second, it's chest pain, so don't mess around, get to the doctor.
