I was diagnosed with relapsing-remitting RRMS when I was 18 years old, 35 years ago, with symptoms occuring every 5-10 years. Symptoms from numbness to tingling lasting for two weeks, always right sided. Growing up in CA, and living in KS, MO, and TX as an adult, I've been very physically active and a runner, completing two marathons. I started taking AVONEX almost 4 years ago. 4 years ago, my right foot would become numb, with drop foot when running only a few miles.
