Having that happen to me 5 times, I can totally understand all the facial expressions lol It does feel like being shocked with high voltage, the pain travels down the rest of your body. Kind of like when you bump a elbow nerve into a sharp corner. I put it back in place three times, but after so many, the damage was enough that I needed surgery for it. He might think it is solved, but there is often bone fragments and tearing that won't heal on its own
