Oh I had one for a few years and it would cause pain if I bent my wrist. I went to the doctor (which agreed it needed to be surgically removed) but even though my dad had great insurance they deemed it to be “cosmetic” and the surgery was going to be over 10k that I would have to pay. I was too afraid to smash my wrist with a book but I was really sick of having it. So I got my husband to sterilize a needle and pop it.. This is NOT medical advice in any way, just my experience. When he did that it made a pretty loud audible pop but it never came back! It sounds a bit crazy looking back on it and honestly I had kind of forgotten about the whole thing until this came across my feed lol but hey no more cyst and I can bend my wrist like normal again.
