Hi anuj,
I read ur question. I also diagnosed ms just few days ago, nd I also prescribed injection avonex. But I wish I could give u exact answer but I don't have any personally experience about avonex coz I don't start avonex yet but I know I will.Just m saying that i found on google that when ever u inject just relax, don't take any stress, u may get flu like symptom so take ibruphen, take rest how much u can, then of course, u can manage it.
