My son is 6 years old, and has had facial paralysis since he was about 1 and a half or two. I never noticed it suddenly but he drooled a lot, had trouble speaking, And I think hearing too. I used to think he heard sounds quietly, but I m beginning to think the sounds are loud now. He had surgery for a chiari malformation right at 2 years ago. His spinal fluid is draining good now, but they found a spot on his spine now they cannot explain. Plus, they still can t tell me why his face droops!!! I need answers... Help me, please.
