This is an article which includes Dr. Sara Axelrod of ENT Allergy Associates in East Brunswick NJ.
Completed extensive studies in Histamine Intolerance. She is an amazing Doctor; listened to me. Discovered I have a potentially harmful medical condition if not monitored. Ran tests even UPenn/Johns Hopkins doctors overlooked. Most of all, has given me peace of mind; I am not imagining this condition.
Uncertain where you are located but definitely inquire. Maybe her office can refer you.Let me know if you need anything else.
GOOD LUCK!
