Meralgia parestetica after hernia surgery

[niazi]

Hello everybody.
I recently got Merlagia parestetica and hope to get your help. I had a laparoscopic bilateral inguinal hernia repair surgery 18 days ago,*and the moment i woke up after the surgery i had a terrible burning pain in my left thigh above the knee.I went to a neurologist and was di diagnosed with MP but he says it will go by itself.He prescribed Lyrica but i still have the shooting pain when i bend my knee in a certain position.Now i saw a neurosurgeon and he asked for an MRI. Unfortunately the MRI didn't show anything. He says it may go by itself and it may not, so it may need a nerve decompression surgery if it does not get better in one or two months.Can you please belp me? I hope it is not needed and i really don't want it, But how long should I wait before deciding to do surgery ?
