I’ve been holding the stick the same way(wine glass style) for a couple years now and I’ve never had any pain.
However, in SF4, there’s a lot of FADCing and all that stuff and I find it puts a lot of strain on my thumb because I use my thumb a lot to do QCF motions and back dashing on a stick.
So yeah, now my whole thumb all the way down to my wrist on the side the thumb is on is sore.
Guess I should rest eh? But I’m just wondering if anyone has had the same problem as me.
