When you have a tendon sheath cyst, if you don’t have significant symptoms and the mass is not too obvious, you don’t need to intervene and just observe the changes in your condition.
Some non-surgical methods can also be used to treat tendon sheath cysts, such as squeezing the cyst, breaking it up with a thick book, or even aspirating the fluid from the cyst with a needle, all of which can be used to treat tendon sheath cysts, but are recommended to be performed by a doctor at a regular medical facility and should not be self-managed.
However, these methods have a recurrence rate of around 50% or more and if these treatments are repeated, they may cause the cyst to adhere to the surrounding tissue, making surgical removal difficult.
Special attention needs to be paid to the fact that squeezing or crushing of intracarpal tunnel and intracarpal ulnar canal tendon sheath cysts is not recommended.
