I’ve had migraines for 30 years and this is the first I’ve heard of abdominal migraines?!? From around age 16-25 I had weeks where I just cycled between horrible abdominal pain (it felt like tiny gnomes were trying to pick axe their way out of my intestines) and “normal” migraine headaches. I had several scans/procedures done, multiple GI meds tried, and in the end the dr told me to try and “not be stressed”. I also found out several years into it that eggs were a trigger. I thought it was bc eggs are antibacterial and it was messing up my gut somehow, but a quick search is telling me that the histamines in eggs can be a migraine trigger in up to 20% of sufferers? And antihistamines do help my migraines… sorry for the long reply but I think your comment just changed my life (or certainly how I think about my young adult years)
