Avonex & stomach ache

I’ve been taking avonex for 2 months now & each week I’ve ended up with stomach ache & feeling sick, however this has been 3 or 4 days after the injection. This week I actually vomited twice in the night (5days after injecting) then felt nauseous for the next 2 days. Does anyone else get this? Have spoken to MS nurse & GP who’s referring me for an ultrasound to check its nothing else as he hadn’t a clue :slight_smile: Thank you!
