Ari.....Your daughter's story sounds just like my life (I'm 62).Yes, the surgery is risky, but believe me, just relieving the pressure of those debilitating headaches was worth the chance. I would have reather died than to go through the rest of my life with the headaches, which just got worse. I'm still having a lot of the problems I had before (balance, fainting, etc), but am told the recovery time is long, but the younger you have the surgery, the better the recovery time is, I've been told. You might go to my messages on Arnold Chairi's Malformation for more input. Good luck to your daughter.
