How to know if it's HI?

I pretty much never get rashes, swelling, hives, etc. Is it possible to have histamine intolerance without those symptoms?

My symptoms:

  • Minor constipation
  • Food intolerances
  • Dairy allergy
  • Wheat allergy
  • Bloating
  • Nasal congestion daily
  • A few environmental allergies but nothing severe
  • Horrible periods and estrogen dominance
  • Insomnia, the type where I wake for at least an hour every night between 3am and 5am and sleep poorly after that
  • Fatigue
  • Highly sensitive to many supplements
  • I react to beef liver (heard this is high histamine)

Hmm probably more, but I'm not sure what else could be related.
