A ganglion cyst is a common, benign (noncancerous), fluid-filled lump found on joints or tendons.
Although you can get them near any joint, 60 to 70 percent of ganglion cysts develop on the front or back of the wrist. Feet, fingers, and areas where you had a tendon or joint injury are the next most common areas.
Ganglion cyst symptoms
Is the lump on your wrist a ganglion cyst? Beyond the appearance of a lump, other symptoms to look out for include:
Lump size. They can be round or oval, very regular (with rounded edges), and typically measure less than one inch in diameter.
Pain. They usually do not cause pain, but if one presses on a nerve you can feel numbness, tingling, or pain in your wrist.
Texture. Although filled with synovial fluid, they can often be surprisingly hard.
Mobility. Although rooted to the joint or tendon with a stalk, they can be pushed around a small amount.
Ganglion cyst home treatment
The good news about treating your ganglion cyst is that 58 percent of them resolve on their own over time.
