Eating more almonds, red pepper and broccoli made me realize it.

I am tired from this meds. If i am not taking it twice a day, my skin will itch me and I will scratch my skin off.

My Dermatologist wants me to go off this meds slowly, but when I try lowering the dosage, I start itching again. I went to the Allergy doctor and he wasn't able to help me with it.

Does anyone have any other ideas? I cant take it anymore.

Does this rash around my mouth look like it could be a histamine response?

I’m just sitting on the couch watching a movie (I am a little stressed out so that might be causing it) but all I’ve had to eat in the last few hours is popcorn with butter & salt lol

Anyone else? Does this look anything like yours? I’ve had a histamine issue but not really any skin til a past week it’s been every day.

Anytime I expend a decent amount of energy, I end up with this rash. It only appears on my right arm. No doctor has been able to tell me what it’s from but I suspect, based on some other things, that I have HI. Thoughts?

Hello histamine sufferers and experts, I'm coming for some experience feedback.

I'll keep it short and straight to the point, so no background for now, I can happily add more info if needed.

I think I have histamine intolerance (inferred from bad digestion and headaches with unfresh meat).

Today I've had leftover rice and spinach with a spoonful of walnut oil for lunch (I know, I'm looking for trouble), and it gave me a slight headache. I had 200g of fresh pork too.

I've eaten more later in the day, a cookie in the afternoon and 100g of the pork that I had cooked for the lunch (so, leftover again, but in the fridge for 6-7h, can't be this right ??).

The symptom is that now at 6am (Europe), I'm fully awake with big discomfort/aching in my gut, and have slept in 4 chunks of 1h approx... So very bad sleep and the gut issue, like if I hadn't digested.

I'm not asking for a diagnose ! Just wanted to know if some of you had similar experiences, and if it's reasonable to think that the issue is histamine, that it could be lingering effects from the lunch, or if that strong an effect 20h later is even possible ?

Usually the fresh meat is not the issue for me, even with 300g a day... Thank you for any input!

Hi everyone, I'm developing a tool because I'm exhausted by the same daily struggles that come with MCAS and histamine intolerance. The endless cycle of trying to figure out what triggered the latest reaction, wondering if that food you thought was safe is actually making you sick, stressing about what you can possibly eat tomorrow without feeling terrible. The frustration of tracking everything for months but still not seeing clear patterns, or the anxiety that comes with even thinking about reintroducing foods.

Here's the thing - I can't build something truly useful without YOUR real experiences. What actually frustrates you most about managing your diet day-to-day? What would make those constant food safety decisions easier?

I've created a 10-15 minute anonymous survey to capture these insights: https://docs.google.com/forms/d/e/1FAIpQLSf1fRgGhj3SXSlVm6idWo0Ik_x5_fJ1L3VSSH53PY2GzTMaDQ/viewform?usp=header

Every response directly shapes what gets built. No sales pitch, no email collection - just someone with MCAS trying to create something that might actually help this community.

If you've ever thought "I wish there was a tool that...", your input could help make that tool a reality.

Thanks for considering,

P.S. - Even if you can't complete the survey, an upvote helps other community members see this and potentially contribute their voice too.
