8 wk Post op femoral hernia repair with some numbness

My 33 yr old daughter had open inguinal/femoral hernia repair with mesh for a strangulated/incarcerated hernia. She had a spinal anesthetic (because she had eaten). Her recovery went well with some discomfort and swelling. She has returned to work full time as an OT. She described to me a continued numbness of the outer labia on the affected side. It is certainly understood that she is still healing and I doubt it is anything to be overly concerned about. I told her just to call her surgeon and ask the nurse about it. I also appreciate that this major surgery may have some lasting implications. Just wondering if there is anything she could be doing if there was some nerve damage (obviously a small or minor nerve) and is this numbness something that is not terribly abnormal at this point in her recovery?
Thank you so much.
