A ganglion cyst causes a typically painless soft skin bump or hard skin lump near a tendon or joint. These very common cysts often vary in size, growing and shrinking in concert with the use of their nearby joint. And can even mysteriously disappear.
What causes a ganglion cyst to develop is leakage of thick tendon and joint lubricating liquid. This liquid is usually sealed in a small compartment, but for some reason it leaks. It’s this escaping fluid that causes your bump or lump to grow.
Why the lubrication leaks in the first place is frequently indeterminable. Although, ganglion cysts are sometimes associated with an injury, repetitive stress, carpal tunnel syndrome and osteoarthritis. And your soft skin bump or hard lump is not a tumor nor a cause of cancer. Nor do they spread.
The sites where ganglion cysts commonly occur include:
- inside wrist
- back of wrist
- last joint on finger
Yet, they can materialize around any joint.
If your soft skin bump or hard skin lump is painless, then no cause for ganglion cyst treatment. However, if your ganglion cyst is causing pain or interferes with joint movement, then these treatment options will be considered before ganglion cyst removal:
- OTC anti inflammatory NSAIDs for pain relief & inflammation
- immobilization ~ wearing a brace or splint may help shrink your lump or bump
- aspiration with a needle removes fluid from the cyst, decompressing soft bump or hard lump
When all else fails, ganglion cyst removal is the alternative via open or arthroscopic surgery. Ganglion cyst removal generally gains you a positive result, although a cyst can recur.
