Established nut allergy. ingested as very small amount. having a reaction with continued vomiting, stomach cramps for 5 hours now. what do i do now?

Get checked: Little nausea med and IV fluid will hep. May need antihistamine/ steroid...

Allergy: Any reaction to a known allergen can be serious, you should have someone take you to the emergency room for evaluation and treatment. If you can keep down Benadryl (diphenhydramine) it may help, but establishing an IV and i v medication is even better. Good luck, and don't delay.
