I had one on the top of my wrist for a couple of years. Excessive activity would make it ache. However, one day, it popped. A few months later it came back, but popped again later. It has not come back again... yet.
My doctor told me that there's a 50% chance of them coming back if they're popped or drained, if I remember correctly. That's one reason why doctors typically prefer to "wait and see" rather than go ahead with surgery unless the pain is absofreakinlutely unbearable.
Waiting worked for me, and the pain was noticeable, but quite bearable (even without pain medication), especially with a wrist splint. So, that's what I would recommend, provided your pain is manageable.
I never could pop mine by banging it against anything, although I tried a few times. I wouldn't recommend it... ouch... WTH was I thinking?
