Hi I Had A Ruptured Brain Anuerysm And Spent Just

Hi I had a ruptured brain anuerysm and spent just over a month in hospital, this was ten years ago. I had an incision from the middle of my forehead to my ear. I am now epileptic and have constant migraines. My question is now I have extreme pain in the area of where the bone flap is and the screws area, is this normal after this amount of tme.
Thank you
Leigh
