Thank you everyone for all of your stories. I'm glad to see that everyone has recovered and improved, even after their injury.
I guess I'll tell my story so I contribute to the thread.
I really started to take the game seriously around the beginning of 2021. I'm not, and still not, all that good. I'm only able to clear 3.7* and 96% 3.5* depending on the map, but I was making what felt like a lot of progress until May hit. Suddenly, my index and middle fingers began to feel pain that built up the more I played. I typically only played for 2-3 hours a day while also drawing as my job, so I tried to keep in mind that I need to moderate how much and how hard I played. Around mid-May, the game became nearly unplayable. I would always have hand pain within minutes, specifically on my finger joins and on palms, specifically the upper parts.
Since then, I've taken a break, only coming on once in a while to satisfy my needs for the game. I don't only blame this game for this issue. I drew a lot at the same time, which is why the pain is far worse on my right hand. I also quit another game that I played competitively that was extremely technical and pushed my hands physically. I visited a doctor to see what was wrong, and they only told me it was a hand strain, which in the last three months, still hasn't healed oddly enough.
Nowadays, I only play to practice accuracy once in a blue moon, but it hurts a lot to not play. My hands continue to ache a lot, even though I don't touch this game or my PC often anymore.
When I get better, I want to make sure to follow the advice on this thread. I can only suspect my reasons for such intense hand pain is just a matter of my playstyle, as well as a variety of other factors. I can't wait to return to this game and start improving again. I loved it, I had fun, and not many games could match that same sort of experience for me. Once again, thanks everyone for responding to this thread. It gives me hope that I can play again.
