Constricting clothing triggers migraine and green mucus

It took me years to figure out that tight clothing could trigger a migraine. Now that I don’t work, I can truly wear something loose fitting 24/7. I don’t wear bras, tank tops, fitted t-shirts, or turtlenecks. Even a winter scarf or a hoodie can be a trigger. I basically live in joggers and a baggy sweatshirt.

If I wear anything even slightly fitted - today, I wore a raincoat over a sweatshirt. Within a few hours I have tingling, aura and now the weird reaction - green mucus in my throat. Clearly, I’m activating something. In the winter time, I might end up with an ear infection and the green mucus in my throat - but not my nose. Now that I am using Ajovy, I might only get 2-3 migraines a month. The constriction trigger will set me up for several days with no relief if I don’t notice the tingling in my throat. I have mentioned the green mucus to my different doctors along the way but is usually dismissed. What is going on?
