About chills, do you get them after the shot only? It does depend on how long you have been on Avonex, if it lasts too long call Avonex alliance number is included with shots of course you can check with your neurologist or regular doctor. Especially if the chills last for more than 2 days. I have been and still am on Avonex, the flu/chills like symptoms eventually go away I rarely if ever, get them anymore.
