Stabbing pains

I've been getting really bad stabbing pains behind my ribs and just under my ribs... I've been to the doctors many times and they can't see what's wrong, I've had loads of tests done and they have come back clear.... was wondering if anyone else knows anything? Or a way to stop the stabbing pains?
