Yes, it broke my heart to read this too. Let's hope for our sake and his that he doesn't need to take too much time off from filming at this stage in the season - he needs to recover physically, but he also needs not to be worrying about the show. There's a balancing act to be done there.

If he's been in pain from a shoulder injury, just imagine what filming the scene with Wo Fat in North Korea must have been like for him... no wonder he's been needing painkillers.

As I said to and_ed, I wish him all the best - I want him happy, healthy, and back on my TV screen shirtless for a long time to come :)
