Have follow up visit: A small % do recur , usually in the first year after surgery , if you want to be sure see your surgeon for follow up visit and ill get the answer.

Pain at Hernia site: Sharp pain after inguinal hernia surgery is most likely due to a mild abdominal muscle strain, but may also be from a recurrent hernia. Most people with abdominal stains feel pain after lifting or exercising. This pain gradually improves with rest. Evaluation by a hernia surgeon is important if the pain is severe or does not go away.
