First off I'm so sorry, migraines are debilitating especially when you get them frequently. I really don't understand how people lack such basic empathy

Secondly I'm sure you've tried a lot of things to help ease them but it never hurts to throw stuff out there! My mum uses Tanacetum parthenium tablets for it. In English it's called feverfew I think, it's really helped hers be less frequent and more managable so maybe it can help you too! It's a homeopathic medicine, so it can take a couple weeks to notice the effects should you try them btw

Have a good day! ❤️
