I am in my 50’s and a type 2 diabetic.For the past few years there have been autoimmune symptoms that remain undiagnosed. Then in May I began to have double vision. We finally have an appointment with Mayo Clinic next week. The diagnosis at this point is a tumor within the first of the cavernous sinus. It is causing problems with cranial nerves 5 and 6. The pain level today is pretty bad and I love in the middle of Momtana. I know that the vibration of the car will be rough but I worry about the pressure changes of flying. Any input would be appreciated.
