I have not been on this forum for quite some time now, as I have found out what my migraine trigger was/ is. I no longer take preventative medication as I don't need to. During covid times I started having really bad stomach pain, nothing was really helping and I felt really awful. I had been tested for coeliac - but it was negative. I was told that gluten was not my problem. It was!!! I went on a FODMAP diet - which was both very strict and very bland. As I was at home and had time on my hands, I was able to concentrate on making my diet interesting and after a few months of excluding and re-introducing all my issues where proved to be very much gluten related.
Fast forward to earlier this year, having been gluten free for over 2 years, but still on propranolol for migraine prevention (was always blamed on vestibular issues and hearing loss) I started having issues where my heart rate was slowing down (I found this out with my fitness watch) and I was feeling really clammy when this happened, had a good chat with my GP and was weaned off the propranolol as she said the tablets could lower my heart rate. I told her I was suspecting gluten was my migraine trigger (I had a couple of migraines and vomiting when I'd eaten gluten by mistake). Once off the tablets I found that I wasn't getting migraines at all anymore.
I know this is not the case for everyone, but I would say if you do have digestive issues and migraines, it might be worth going down that avenue. I have actually found recently there is medical proof that migraines and gluten intolerance / coeliac disease are linked. I know within a few hours if I have eaten the wrong thing - I get a migraine that makes me sick and totally wiped. But at least for me now it is only a case of a week feeling rough as opposed to feeling really rough all the time!
If this helps one of you get better then it's totally worth it 🙂
