One feature of the Nintendo Switch that makes the console stand out is it’s very clever controllers; the Joy-Con. Not only can they be used in a multitude of ways to suit your play style and the number of people you are playing with, both the left and right controller also boasts Nintendo’s very own HD Rumble.
A man in Sydney, Australia named Chris on Reddit is saying that the HD Rumble from the Joy-Con helped him find a tumour in one of his hands. When playing Mario Kart 8 Deluxe, and most notably when picking up in-game coins, one of his palms started to hurt. Over the course of time, it got worse but never caused him nearly as much discomfort when playing on his Xbox or PC.
“I’m a programmer, and it was a pretty busy time at work, so I just put it down to [a repetitive stress injury] or something similar,” Chris told Kotaku over email. “I thought maybe it’d go after a few quieter days.” But the pain gradually got worse and so Chris went to the doctors and is now due for an operation to remove a small but a painful tumour in his hand. He said if it wasn’t for the Switch, he would never have visited the hospital to go and get it checked out.
