Hello, ive been in tyruko for a year now and it's been a huge help, I was put 9mon it as soon as I was diagnosed. My recent blood test came back with a JCV positive. I know there's very low risk of anything coming out of it, but im now slightly terrified and don't know what to do. I've been advised that I can stay in ir for another year, but im not sure if I want to risk the idea of the JCV or change to some other medication and risk getting worse ms symptoms. Anyone got any advice?
