@mshackney , Avonex is one of the interferon-based DMDs, so it could give you some flu-like symptoms shortly after the injection. This side-effect doesn't last long, e.g. if you have the shot in the early evening, you may get the symptom later on that evening, but they'll be gone by the morning. Just don't stress yourself out about it. It's not worth the adverse effects of the stress. :wink: Good luck with it.

Thank you, won't delay then - delaying will probably stress me out more....
