TT - as you probably know, there’s neither a reliable nor magic “cure” for ganglions. Yours, being on the back of your wrist, is one of the more common locations. It’s not cancer and there’s no urgency for you to do anything about it, except from a cosmetic stand point. That said, the hands are pretty important. You notice immediately the “prison tattoos” love and hate on the back of peoples hands, etc. So, what do you do? The night time cock up wrist splint has a small but loyal following as does the “bible cyst” camp. Even when I operate on them the biggest complication I quote is recurrence. There’s no rush for you to make any kind of decision.
