Why does it mean when I get a reoccurring sharp pain in my right wrist. I feel a lump?

Ganglion cyst. You may have developed a ganglion cyst which can cause a cyst like lump at a joint line. These are common in the wrist and usually go away on their own. However, if the pain is severe or if you have had any trauma see a doctor for an exam. You may need an xray.
