Sudden Allergy Attack in the Afternoon - What Could Cause It?

I’d ask your landlord if anyone recently moved in with a pet! Ventilation can carry allergens

Have you heard of mast cell activation syndrome? It sounds like it’s worth looking into. In the simplest terms, it’s like an ongoing allergic reaction. Around 3-4pm your body naturally has a “histamine dump,” which often causes people with this condition to feel crappy around that time of day, myself included. Try finding an allergist/immunologist who specializes or at least has heard of MCAS. It’s more common than people realize but it was only discovered ~15 years ago so most practicing doctors haven’t learned about it

I wouldn’t think it’s anything I’ve been eating as I don’t typically eat within super close proximity to the attacks, it’s also the same objects (in my bedroom) I’ve been surrounded by the majority of the day and it’s cleaned and vacuumed frequently. I will keep note of what I’m doing around the time of the attacks though and see if I can get to the bottom of it! 🖤

Are you eating something or using something at that time that could be triggering it?
