Side effects: I think each body is different. For me, I get a sinus infection and a uti that both hit around the same time, 3-5 days after the infusion. The day of infusion I usually get really tired, and just drained of energy and that lasts about 2 days.

I also have really bad joint pain but I don't know that I can blame that on the ty seeing as I was having that issue long before I stared it. But on the plus side, my last 2 MRIs have shown no new lesions.

Some people feel great with it and can tell when they are getting close to their infusion. Personally, it hasn't happened for me. Good luck though. Glad to hear the headaches are gone. I know that is a relief.
