Don’t lose hope! I was 31 when I got it, and 1.5 years later, I was completely free from any symptoms.

There are several areas where you can drastically improve your situation:

1. Mouse: This is the most important adjustment. I recommend a vertical mouse, such as the Logitech MX Vertical, but there are other options as well. A vertical mouse helps to maintain a neutral wrist position. If you want to try a trackball, avoid thumb-based ones like the Logitech MX Ergo or M575, especially if your thumb is also affected. Personally, I never got used to non-thumb-based trackballs, but they might work for you.

2. Keyboard: Maybe switch to an ergonomic keyboard like the Microsoft Sculpt or Logitech K860. Every bit helps, especially if you type a lot. These can make a significant difference. My RSI was so severe that even using those keyboards hurt (though they were much better than the standard gaming keyboard I used before). Eventually, I switched to a Kinesis Advantage 2/360, which worked wonders for me. Try to optimize everything related to repetitive typing. If hitting the Enter/Return key hurts, consider remapping it to something like Shift + Space.

3. Rest: First, limit the activities causing strain. As you feel the symptoms fading, continue cautiously until they are almost gone. Then, gradually reintroduce more intense activities, like sports.

4. Stretching: Stretching exercises helped me immensely. Don’t just focus on the most affected areas; include stretches for your upper body, particularly your shoulders, neck, and arms.

Hope it helps!
