🌿 Overview
A ganglion cyst is a soft, fluid-filled lump that forms near a joint or tendon, most commonly on the back of the wrist. It's harmless (not cancer) and often changes size or disappears on its own. Treatment is only needed if it causes pain or gets in the way.
The cyst is a balloon of jelly-like fluid connected to a joint or tendon sheath, often appearing after repetitive use or for no clear reason. It may ache, especially with wrist activity, or press on a nerve to cause tingling, but many are painless.
The reassuring news is that many resolve without any treatment, so a 'watch and wait' approach is reasonable. Resting the joint and easing aggravating activity help any aching. The old folk remedy of striking it with a book ('Bible cyst') is discouraged — it can cause injury. If it's painful, growing, or limiting, a doctor can drain or remove it.
