Hi and welcome to HCM. Thank you for your querry.
It can be hernia
recurrence,this isnt unusual but also there could have been nerve damage
during the surgery and this is also not uncommon complication. It ca also be mesh infection
but it would manifest with some other symptoms. You can do ultrasounds to confirm is there hernia recurrence or not. Nerve damage can be succesfuly treated unfortunately. Wish you good health.
