Numbness of the perineum after varicocele surgery is likely to be a normal part of the recovery process, mostly due to the fact that the local nerve function has not yet recovered. If the symptoms persist, it may be a sign of nerve damage. 1. Normal physiological recovery process: the surgical process will cause local tissue damage, so it will stimulate the local nerves and blood vessels, etc., postoperative swelling and numbness is normal, most of the recovery process will be self-recovery, do not need special treatment. 2. Nerve damage: If the symptoms persist, it is possible that the nerve was damaged during the surgery. If the symptoms persist, you can choose some nerve-nourishing drugs under the doctor’s guidance to treat the symptoms. If the numbness is only transient, most of the numbness will recover by itself. If the symptoms persist, it is recommended to go to the hospital and use the medication under the doctor’s guidance.
