de Quervain tenosynovitis causes pain in your thumb joint because it affects two thumb tendons. These tendons are called the the abductor pollicis longus and the extensor pollicis brevis.
The tendons from these two muscles travel side by side. They pass through a synovial tunnel near the thumb side of your wrist.
Because of the coating in this tunnel which is called tenosynovium, it allows the two tendons to glide easily back and forth as the thumb moves. When the tenosynovium becomes inflamed along with the tendon, this is called tenosynovitis.
