Weird swelling in wrist with pain and lump that is squishy?

Ganglion cyst. While more info is needed, it sounds like you have a ganglin, or "bible" cyst. These are very common at the wrist. They are small balloons of tissue and fluid from the joint, and tend to get bigger and smaller. Sometimes thy have no other symptom but if they hurt, you at need treatment. That an nclude trying to drain it or inject it. Used to be hit with a bible-but don't try that!
