In 2006 eye dr. sent me to a neuro for a head tremor. Neuro sent me to Mayo Clinic, they said not MS yet. The tremor went away over time. Then wonderful 2013 rolls in. That year had double vision, didn't tell anyone for the 1st 4 days. My regular Dr. sent me to neuro who diagnosed me and back up to Mayo for 2nd diagnosis confirmation. This started me on copaxone for 7 months. Finally I talked my neuro into trying tecfidera. I am still presently on tecfidera and thank God no problems other than fatigue. 1 day at a time.
