I would strongly suggest seeking advice from a medical professional (if you have the means) rather than advice from strangers on the internet. I'm I can't say what advice a professional might have, because I'm not a medical professional, but it will almost certainly be better than what anyone here can give you.
And if you're not sure if your problem is worth talking to someone about, that in itself is a sign that something is wrong. I know it's hard, I've been there, but please understand it is the best course of action (again, if you have the means).
So what were everyone's thoughts on the original? Do we think the new one will be better?
I had two of the original steam controllers. I don't think I played a single game with them.
