multiple sclerosis
"I've been on Gilenya for quite some time now. At first, I had no side effects at all. Lately, however, I've been getting random symptoms and not sure if they're directly related. My hair has gotten thinner, my eye's sensitivity to light is a bit off, I've gotten gingivitis and been getting mouth ulcers a lot. I'm getting a bit worried, but so far haven't had an attack since I started taking the medicine."
