I inherited them from my mother. Her twin sister and my sister also suffer with them. My son gets them from time to time. My granddaughter has been diagnosed with abdominal migraines. I had never heard of that b4.

My mom's mother had them.

It runs in the family from my dad's mother to me.

In my family, it is mostly female, but my son gets them as well. I don't have a lot of living Male relatives, so I can't give you a definite answer.
