Complications & Risks
Any surgical procedure has an element of risk attached to it and occasionally things do not turn out as well as expected. Fortunately they are rare and seldom serious.
The ganglion may recur in 20% of the cases. The skin around the scar may be permanently numb after the operation. Wound infection is another possible complication.
A rare complication of injury to the hand, including surgery is “chronic regional pain syndrome”. The hand is disproportionately painful and stiff with some swelling. You should seek advice promptly if you experience such symptoms. This can last for many months and is difficult to treat.
