RSI, or repetitive strain injury, can affect anyone who uses their hands a lot, repeating the same movements. This could be from working at a computer all day or spending an extensive amount of time scrolling on your phone. At first, symptoms like pain and tingling may go away once you stop overusing your muscles. However, without treatment, including lifestyle changes, symptoms are likely to get worse and may even become too severe to move.
Don't hesitate to see your doctor—just a few days off is likely not enough to stop RSI. Part of the solution is to take regular breaks throughout the day. Stretch your arms, wrists, and fingers every half hour to keep them from cramping. Practice good posture when sitting; your head and back should form a straight line from ears to hips. Don’t let your wrists bend to one side—keep them in line with your forearms, and keep your fingers slightly curved over your keyboard.
Avoid using splints or a wrist rest, as both can interfere with natural movement and blood circulation. You might also consider investigating the Alexander Technique, an approach to movement aimed at better posture and body mechanics, which can be helpful for RSI.
