The tendon sheath cyst does not go through treatment to return to the main three situations, as follows: first, the tendon sheath cyst self-healing, that is, the cyst absorbed and dissipated by itself, local will not produce any symptoms, mainly seen in the cyst is relatively light patients. The cyst can gradually be closed by itself to achieve self-healing of the cyst if you pay attention to the protection of the cyst site and do not perform too much strenuous exercise, and the fistula between the cyst and the joint cavity is not very large. Second, the cyst is relatively stable and does not undergo any changes, the cyst is moderate, not too big or too small, and it is relatively long, the wall of the cyst is thick, the fistula is relatively stable, and it can reach a relative balance, the cyst does not have any changes, it persists and neither disappears nor becomes bigger. Third, the cyst aggravates, the tendon sheath cyst will gradually become larger and compress the surrounding tissues to produce corresponding symptoms, such as pain or dysfunction. In short, the tendon sheath cyst is not treated is these three regressions, according to the specific situation to take the appropriate treatment approach.
