Hi . Your concerns are certainly understandable when dealing with an autoimmune condition like MS and facing something like radiation. I can't personally speak to this issue, but I do want to share with you that we have a sister-site for MS at https://multiplesclerosis.net/. I know there are multiple people there who have written about experiences with radiation and you can also ask questions in the Forum section there. I also know that it is important to get the specialists to coordinate care (my wife, Kelly, was diagnosed with juvenile RA at age two, 46 years ago). Have you had a chance to speak to your neurologist about the potential for radiation therapy? Hoping you can get some answers and the treatment you need soon. Best, Richard (Team Member)
