The first time I learned I might have MS was when I went to urgent care for my second steroid infusion after losing vision in my right eye and being diagnosed with optic neuritis. The on-call doctor, appearing on a video screen, asked, "You're hear for an MS relapse?" Umm..., "I haven't been diagnosed with MS," I said. I then spent months getting MRI's, a spinal tap, lots of blood work, a chest X-ray, and meeting, over and over again, with a neurologist and MS specialist.
