[b][size=150]Hello! Just joined the Forum. I am looking forward to visiting and reading and maybe answering a question or two if possible. I have had MS for 12 years now and had my worst exacerbation in 2010 that left me using a cane and scooter and unable to drive from optic neuritis. I have other issues too but hesitate to get too graphic. I have been on Avonex, Rebif, and Copaxone. I stopped injections recently to start Tysabri treatment.
