<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had a trapieziectomy operation 10 days ago and as a result the back of my thumb below the nail is numb. I have a heavy bandage on and consequently cannot touch any further down the back of my thumb to determine how far down the numbness goes Could this have been caused as a result of damage to the nerve during the surgical procedure and if so can I expect the numbness to eventually go?  <response>: Hello, Since there is numbness for last 10 days, nerve involvement is evident, now the prognosis depends on whether the nerve affection is partial or complete. There is a high chance of recovery in a year or two if the involvement is partial, in case of complete resection there would not be and recovery unless repaired surgically. We need to get a nerve studies done before going for surgery to elaborate the extent of nerve injury. Hope I have answered your query. Let me know if I can assist you further. Take care
