RSI and CTS are not that common in the community, actually RSI became a meme and you shouldn't think that every 2nd pro gets RSI at some point lol...I don't think it's that serious. I haven't got any numbness or anything and my wrists feel fine. It's really just a bruised feeling in my knuckles and I was wondering if anyone has ever gotten anything like that.
If you are noticing pain, meet a doctor. It may not even have something to do with your wrist. I had wrist pain and hand numbness myself and guess what it was. It was a nerve disorder in my neck, had to wear a scarf and it was all gone within a few days.
tl;dr: meet a doc
