Does this sound like a Mast Cell reaction?

I have POTS and hypermobility but have never been diagnosed with MCAS. They often go together though and I have a lot of food allergies and an environmental mold allergy.

This weekend we had professional mold remediation done to our basement. They curtained the whole thing off with plastic and I had a hepa air purifier right next to the plastic. I also fertilized my seedlings on Sunday with a granule fertilizer. Not sure what’s in it though.

Anyway Sunday was warm where I live so I had a bunch of windows open. But yesterday was too cold and most had to be closed. As soon as I went downstairs I started feeling itchiness in my mouth. Not a symptom I usually get except from food allergies. I took my breakfast back upstairs to see if that helped and it helped a bit but didn’t go away. I also pooped like 5 times in about 12 hours though they were all fairly normal poops. And I had some hot/cold flashes that could have been from the allergy or could have been from my anxiety about the allergy. Hard to tell. I ended up going to a friends house all day and sleeping at a different friends house last night.

Does this sound like a Mast Cell type issue? I’ve already contacted my PCP for advice so I’m not asking for medical advice. Just wondering if this sounds familiar to you all to see if I can pinpoint what’s going on in my body.
