question: My great-niece is 11 and has suffered from continually-worsening migraines for about three years. The only other symptom that she experiences is that she is usually not able to have a bowel movement during the same time. If she does have one, a very small amount is produced. The migraines are getting much worse. Could there be any connection between her severe headaches and her bowel issues? My niece has had her to several doctors and they have tried various medications and diet restrictions, as well as allergy testing.
