Yes, I agree with feelbad. I had an x-ray initially and it didn't show anything. I had a T6-7 herniation. I was treated for muscle spasms - which I did have for 6+ months. But, that was only a symptom. I would not wait that long. The pain going around the ribs is called radicular pain. It is classic of a nerve being compressed. If this doesn't go away with in a week or so with rest, ice and anti-inflammatories, I'd really push for an MRI. You don't want that nerve to get used to being so grumpy. Believe me...
It's worth trying the rest, ice, meds, and PT though. Do keep a pain journal. It's kind of a hassle, but it's really useful to doctors. Describe what makes pain worse and what relieves it in any way. Even if it never goes away completely, what makes it subside. What can you do that makes the pain horrible? Be specific. This is really helpful information.
Good luck. Thoracic issues are unusual, but there are a few of us floating out here...
