Kesimpta symptoms

I started Kesimpta last week Friday. After injection I had shivers and fever for couple of hours and the weird side effect I experienced was burning feet. I felt my feet were on fire. Around midnight flu symptoms settled but my feet and toes have kind of numbness since. I told my nurse but she doesn’t know anything about it. I am now anxious about it and wondering if it is a side effect, reaction or I am experiencing a relapse. Any one else had this experience? #Kesimpta #sideEffect
