If he keeps using his hand this intensively then he might form Arthritis. This seems to already be happening though...
If he wants to get rid of this RSI then he'll need to take anti-inflammatory medication, most likely. This should help all of that muscle swelling go down. The muscles probably swelled because, like he said, he uses the keyboard and the gamepad a lot.
Get well soon, Sakurai!
