Overload tendons are being created inflammation within the tunnels / tenosynovitis which results in the thickening and an increase in friction between the tendons and their pochewkami and extensor retinaculum thickness. This causes the pain and restricted mobility of the thumb. Symptoms then when we perform certain repetitive tasks that require bending and straightening your thumb.
