Hi. Thanks for your query. Abdominal migraine is a rare diagnosis and can be said only if all the investigations related to abdominal pain are normal. This is a diagnosis by exclusion. I would advise the following:: Laboratory investigations: Blood- routine , sugar, kidney functions, liver functions, thyroid functions Urine- routine, microscopy- for porphyria ( simple test of putting urine in a glass container exposed to sun to see the change in color) Ultrasonography with color doppler mode- vascular studies of the arteries and veins, also can be done by contrast enhanced CT abdomen or MRI angiography. If possible to get this done during the attacks. -Enteroclysis to see for intestinal obstruction -All the other investigations as the Gastroenterologist may feel necessary as per your detailed history and examination and his suspicion... You can be labeled as migraine only if all the investigations are normal.
