Started Enbrel - fever normal day after?

Hi - I have just started Enbrel again, after 4 years without. I took the first injection last night. Today I am freezing cold. The room says 23.5 degrees celsius, but I am frozen. This usually means a mild fever for me - but I have no thermometer at work. I seem to recall that one of my drugs gave me a mild fever the day after, but I cannot remember if that was MTX or Enbrel. Thoughts?
