De Quervain's tenosynovitis is inflammation of tendons on the side of the wrist at the base of the thumb. These tendons include the extensor pollicis brevis and the abductor pollicis longus tendons, which extend the joints of the thumb.
Treatment for De Quervain's tenosynovitis is aimed at reducing inflammation, preserving movement in the thumb and preventing recurrence. You may start doing exercises when it is not painful to move your hand. Only stretch as far as your own edge. Don’t force yourself into any position.
Make sure you refrain from doing any abrupt movements. Keep your movements even, slow, and smooth.
