So I wake up last night with this odd burning feeling on my left side. If I was to describe exactly where this feeling was coming from, it would be dead smack middle between my left shoulder blade and chest. Never having heartburn before, is that what it is?
I've always experienced heartburn in my upper stomach right below my sternum, where you're noticing the pain doesn't sound like heartburn to me. I'm certainly no doctor though, might not be a bad idea to see one.
