Hello, I have MS but have been symptom free for many years. I just found out that I have 2 meningiomas that the doctor wants to treat with gamma knife soon. I have double vision, from one of the tumors. I am so scared because I’ve read that any radiation even gamma knife can cause demyelination of the brain and cause a resurgence of sometimes severe MS symptoms. Has anyone else had gamma knife with a diagnosis of MS too. Thank you.
