"I have had MS awhile, DX in 2000. I have taken interferon,tecfidera and controlled. I decided to try Gilenya this summer,a month in I started getting numbness under both feet. I had never experienced anything like this before. Medicine was the only change.It got so severe both feet were completely numb. It felt like i had pads under my feet.After trying oral and iv steroids no improvement i was so frustrated and didnt know what to do. No new activity on myMRI. Because numbness can also be associated with MS this can be confusing. I had no other choice but to stop Gilenya to see if that was causing it. Funny enough after 6 days into stopping it the sensation started coming back under my feet and 70% better. Now it's almost gone!"
