Hi guys! So last night I experienced a second episode of immediate post injection reaction with my Brabio medication. My symptoms occurred within seconds and included sudden warmth across my chest, hives at injection site, tightness around my neck and jaw, palpitations and intense lethargy and "brain fog". I experienced the same thing last year and was told most likely it was a once off and to continue taking the medication. Has anyone else experienced these side effects? Its a very scary situation which requires an ambulance trip to my hospital. The A&E doctors where puzzled and I find im having to do my own research on this. Any advice would be greatly appreciated!
