Mouse Wrist Tendinopathy - #3 Wrist Pain with Gaming
By Dr. Elliot Smithson, PT, DPT, MS, ATC, EMT·
Quick answer
Mouse wrist tendinopathy is pain on the pinky side of the wrist from an irritated tendon, the extensor carpi ulnaris. It is the third most common pain pattern our team sees in Fortnite and other FPS players, whose games demand constant mouse movement and clicking.
The three main causes are poor wrist and hand conditioning, wrist position and how you hold the mouse, and playing too long without breaks. Management is a daily routine: strengthening in the morning or before bed, stretching after or between sessions, a neutral wrist, and regular breaks.

If you made it here you are likely dealing with pain at the pinky side of the wrist as shown. This is the third most common pattern the 1HP staff has seen with not only fortnite but many FPS games. This was also confirmed with the questionnaire referenced in the main guide. This pain pattern is what the team calls "Mouse Wrist Tendinopathy" (Extensor Carpi Ulnaris Tendinopathy for those working as support staff)
As mentioned it is a wrist & forearm tendon issue not specific only to fortnite but also many FPS games (occurred with a NIP player we had treated who developed mouse wrist tendinopathy due to how he was holding his mouse) Commonly FPS games require consistent mouse movement & high mouse APMs. The tendons irritated involve the muscles which help in index/middle clicking along with moving & lifting the mouse. These are some of the movements the muscle is involved in!
