hi, i am 16 and have been in and out of the hospital for the last couple years due to a series of concussions from football, i was recently told i have a chiari and that i would see a NS in 4-6 weeks. the pain is unbearable, and i have memory loss, dizziness, muscle fatigue, extremely painful headaches starting in the back of my head near the base of my skull. With all of these symptoms, will i most likely need decompression surgery? Please help. -Nick
