Severe Allergic reaction to Ajovy or CRGPs

I suffer from migraines with aura, anywhere from 15-20 per month, every month. They have gotten increasingly worse over the last 7 years. I have tried multiple treatments, currently on topomax and botox was not successful at all. After 1 year of botox I didn't have any noticeable decrease. My doctor decided to try the CGRP treatment, Ajovy. I had what would be considered a severe allergic reaction. My throat went numb, felt thick and tight, my tongue went numb and felt thick and heavy, my face went numb, my vision started blurring. I developed a rash on my neck within 30 minutes of the injection, which I didn't even get the majority of the medication. I even called 911 and had an ambulance come. By the time the ambulance came most of the symptoms had subsided. It then triggered one of my worse actual headaches I've gotten with a migraine in a long time. My doctor and I are considering trying one of the other CGRP medications (supervised). I'm wondering if other people out there have a had a severe allergic reaction similar to mine and then safely used one of the other medications.

I've done as much research as I can with the info provided by the manufacturers and it just doesn't say. Only "if you are allergic to ingredient "x" or any of it's other ingredients...
