I have bad reactions to most medications. ( if there's a side effect listed I will have it and then some) I was on betaseron for 4 months before I had such a severe reaction that I became paralyzed with the worst pain I've felt in my life( and I've had kids) And stopped it immediately. Side effects stopped within a week but the stress brought on the biggest relapse yet and I have not gotten better. I look at medications and have to weigh the side effects with how I feel now and it's terrifying to try something again. My doctor recommends gilenya most but has also listed tecfidera, lemtrada, and aubagio.
