LeBron James' right elbow mysteriously swelled to the size of a tennis ball a few weeks after the 2017 NBA Finals.

X-rays came back negative and an MRI showed no structural damage.

The injury was nothing like the one that plagued him during the 2010 playoffs.

"That was different. That was so different. I would get to here," James said forming his arm in an L-shape, "and get right here and it would just lock."

James isn't sure how the injury happened.

"I don't know where it came from," James said. "I was working out in L.A. in late June and my wife was like, 'What's wrong with your elbow?' I'm like, 'What?' ... The weirdest s---."

James changed his shooting motion to minimize the discomfort in his elbow.
