I Was Recently Diagnosed With MILD Chiari Malformation. I Am

I was recently diagnosed with MILD Chiari Malformation. I am 49 years old. My family and I are going to Disney World soon and I was wondering if it is safe for me to ride the rollercoaster rides and/or the Tower of Terror ride with my kids? We are also FLYING to Orlando and I had heard that airplanes can cause a problem too. Is this true?
