Leaving it alone is a safe choiceStrong evidence
NHS England's Evidence-Based Interventions guidance says wrist ganglia should be treated only if they cause pain, tingling or numbness, or worry that they might be cancer, and that 'doing nothing will not be harmful'. Drainage comes first; surgery only if that fails and the hand is restricted. An NHS hand unit doesn't routinely offer surgery for a simple wrist ganglion, because of the scar, the chance of it coming back and occasional nerve damage, stiffness or long-lasting pain.
The NHS suggests ibuprofen, and a wrist support or compression wrap, if it hurts with use, and says not to try to burst it.

Draining it (aspiration) often doesn't lastStrong evidence
Under local anaesthetic, a needle draws the fluid out. It confirms the lump is a cyst and can ease symptoms, but it often refills: across 12 studies, on average 59% came back; an NHS hand unit says up to 8 in 10, within weeks or months; and after a single needle puncture, 19 of 34 came back, on average 43 weeks later. NHS England's guidance says drainage cures a minority, about 3 in 10. In studies that weren't trials, drainage did no better than reassurance.
Adding a steroid injection didn't help: in a randomised trial both approaches worked in 33%, and a 2026 review found too little evidence to support it. Splinting after drainage didn't help either. Even so, people are often content: 95% of 21 people were satisfied 6 years after drainage, whether or not the cyst came back.

Surgery: it comes back less often, with more downsidesStrong evidence
After removing the ganglion and its stalk through a cut (open surgery), it came back in 21% on average across 14 studies, with complications in about 14%. NHS leaflets say up to 2 or 3 in 10 come back. In two randomised trials, surgery cut the chance of it coming back by 76% compared with drainage.
Keyhole (arthroscopic) surgery averaged 6% recurrence and 4% complications, but in better-quality studies keyhole and open surgery had similar recurrence (7.9% and 9.8%), and a 2026 review of 6 studies found no difference in recurrence, pain or satisfaction, with a quicker return to work after keyhole surgery. In a small randomised trial of palm-side ganglia, recovery took about 6 days after keyhole surgery against 15 after open surgery.
The downsides: in a UK study of palm-side ganglia, 20% of those operated on had a complication, and they took 14 days off work on average. NHS England's guidance says hand use is restricted for 4 to 6 weeks. After 5 to 6 years, symptoms were similar whether a ganglion had been removed, drained or left alone, although people were more satisfied after surgery for back-of-wrist ganglia, and 1 in 4 wrists stayed weak whatever was done.

Children: watch and wait firstEmerging evidence
In children, most ganglia go on their own, often within 1 to 2 years. An NHS children's leaflet says most can safely be left, offers drainage if one causes pain or discomfort while noting that it often comes back, and says surgery still carries a chance of it coming back.

Training with a ganglion: no study, but no reason to stopMixed evidence
No study has tested exercise for ganglia. Exercise won't make one go away, and there's no evidence that training causes one or makes it worse in the long run, though it may ache more after heavy use and settle with rest. For repetitive strain, the NHS advises against resting the area for more than a few days, because it becomes weaker and less flexible. So keep training, and change the positions that press on the lump or bend the wrist fully over it (our suggestion).

Seed ganglia and mucous cystsEmerging evidence
NHS England's guidance says a seed ganglion at the base of a finger can be punctured or drained, and a mucous cyst by the nail is only operated on if it keeps leaking fluid or is deforming the nail.
