| | Rebif side effects
Does anyone know usually how long after the injection you could have the side effects? Just started taking Rebif, first injection was about 36 hours ago. Just now start feeling cold, chills, muscle spasms. Could it be the injection after this length of time. My arm, the injection site feels fine but also notice today it has red area around the site. All help, suggestions will be very much appreciated. I'm a nurse but with all of this I feel like a fish out of water. Thanks!
