Pediatric tendon sheath cysts can be partially kneaded open, allowing the contents of the cyst to flow out and the cyst to subside, but there is a possibility of recurrence, so avoid treating the cyst on your own.
The content of tendon sheath cysts is the accumulation of synovial fluid in the tendon sheath to form a jelly-like viscous fluid. After the cyst ruptures under external forces such as kneading or impact, the content will flow into the surrounding tissues and will be gradually absorbed, but it cannot be ruled out that tendon sheath cysts will recur after a few months or a few years.
It should be noted that not all tenosynovial cysts can be ruptured by kneading, and those that are too small or hardened cannot be removed by kneading.
Regardless of whether or not kneading can rupture a tendon sheath cyst, the complete removal of a tendon sheath cyst requires medical attention.
