Side effects after taking Tecfidera - Has anyone else had this?

I was diagnosed in May with MS. The medicine Tecfidera is what I was prescribed for it. I still have headaches everyday. I’m having loss of feeling in my right arm and leg again. This hasn’t happened since April when I thought I had a stroke. I have 2 friends with MS and they have never had this to happen to them. Anyone else here ever had this to happen to them?
