I'd have to think the jaw pain is from grinding teeth. My dentist at one point thought I was doing that (turns out I am a daytime clencher instead!) so I did some research and waking up with pain that gets better as the day goes on is a classic symptom of nighttime grinding. His dentist should have him fitted for a night guard to help save his teeth.
