That sounds like an abdominal migraine. I've been a migraine sufferer for 13 years and that euphoria the day before is how I know it's coming. How do you feel the day after the pain? Feeling utterly exhausted afterwards is also a common symptom. I usually get the migraine pain in my head, but I've had a few abdominal migraines and they sound very similar to your symptoms. Maybe something to look into.
