Thanks again, David. Another couple of quick ones for you:

Also, should I really go get an MRI? Or is the x-ray + other work enough?

One thing that scares me about MRI and similar procedures is that it always seems like they turn up problems, and I’m worried someone’s going to prescribe surgery or something crazy like that. Of course, I’ve never had an MRI so I definitely don’t know what I’m talking about. Any thoughts on that?
