Okay, I have been injecting betaseron since 2002. I never have to take a tylenol or anything and have never gotten the "flu" type feeling after taking a shot.

The other night after a shot I went to bed and woke at 4 a.m. with the chills, terrible headache, achey body and just felt terrible til mid morning.......then I was fine.

Now I've experienced this a couple times before, but can't remember if it was after a shot or not. I haven't come down with anything like a cold or infection.

My question: Anyone else experience this "flu" type feeling after a shot after being on it for a long time? Its was my understanding that these were early side effects of the drug.....I'm wondering if this is possibly what I experienced?
