How do I know if I should perform a histamine test?

Do you suffer from skin rashes, itching, swollen eyelids or legs, heavy sneezing fits or diarrhoea after some foods? These could be indications of a histamine intolerance.
Especially hard cheese (such as Parmesan), ketchup, tomatoes, sauerkraut, spinach, legumes or wine are known for their high histamine content and trigger histamine-related symptoms.
