I sprained my hand and got a pimple on my wrist. It doesn't hurt or need it. What happened?

Refers to cyst diseases that occur near joints and tendon sheaths. The most common clinical manifestation is dorsal cyst of wrist and ankle.

Most of the causes are strain or stagnation of qi and blood, blood stasis and phlegm stasis after injury. Modern medicine thinks that it is a hernia caused by synovial fluid oozing from joint capsule or tendon sheath, or a hernia caused by local glial degeneration of connective tissue.

Symptoms are mostly attached to joint capsule or tendon sheath, which can communicate with joint cavity and tendon sheath. Single or multi-chambered, with gelatinous mucus in the capsule. There is a small lump with slow development outside, which is round or oval and higher than the skin surface. It was soft at first, and I could feel a slight fluctuation. Long-term fibrosis can harden, mostly asymptomatic, and a few people have soreness, pain or conscious powerlessness. People born in the nest of Yueguo are as big as eggs when they are straight, but they are not easy to feel in the depths when they bend their knees. Some tendon sheath cysts can disappear on their own, but for a long time.

Treatment principle: Tendon sheath cyst can sometimes be crushed and ruptured to heal itself. There are many clinical treatments, but the recurrence rate is high.

1. Tendon sheath cyst can disappear by itself, but it takes a long time.

2. Superficial cysts can be squeezed, ruptured, squeezed or acupuncture by external force, and can be cured by self-suction, but it is easy to recur.

3. Non-surgical treatment: usually, after the contents of the capsule are discharged, 0.5ml of prednisolone acetate is injected into the capsule, and then pressure dressing is performed. This method is simple, less painful and has a low recurrence rate.

4. Surgical treatment: finger tendon sheath cysts are generally small and difficult to puncture; Tendon sheath cysts that recur many times in other parts can be surgically removed. The cyst should be completely removed during the operation. If tendon sheath appears, some connected tendon sheaths should be removed at the same time. In case of synovial hernia of joint capsule, it should be ligated and removed at the root to reduce the chance of recurrence.
