Hello everyone! I was diagnosed w/ MS April 2012...been on Avonex for 7 weeks now...at the full dose for 3 weeks, titraited for the 1st 4...these side effects are CRAZY!! Has anyone had this happen...they get the injection, feel crappy for a couple days, feel better, but suddenly feel crappy again for a few hrs?? Especially facial flushing?? Scared me to death!! My one Dr feels I had an allergic reaction, whereas my neurologsit says he thinks I picked up an infection. Well...it only lasted (the flushing) for like 2 hrs...then gone! Thanks for any advice...
