I’m hoping this is an ok place to ask a question like this.

I recently had to get a new mouse because my old one broke. I couldn’t get exactly what I had before but I got something fairly similar. However, I’ve been struggling to tune it to feel good to use. It’s actually been putting a lot of strain on my arm even after short play sessions.

Does anyone know what might be causing this and how to fix it? What kind of things should I do to find the appropriate sensitivity/settings or maybe I’m holding my arm differently for some reason or maybe I need a different kind of mouse?

If it matters, here’s the old and new mice:
