Brad, it sounds like your pain might be too low for this to be a
concern, but I've heard that symptoms of a heart attack can be
discounted or thought to be some other condition.  I take it you
don't have health insurance?  Is there any kind of advice line you
can call to at least talk with someone and get an opinion from a
medical professional as to whether this needs to be checked out?  Of
course we're all concerned, but none of us are medical professionals.
