I'm not sure if you caught my point: I was wondering if you've checked for yourself if it might also be mast cell activation syndrome, MCAS.
Cos that has multiple chemical sensitivities too.
But additionally allergy type / histamine type intolerance reactions of the outer and "inner" skins to these, often to foods and meds too.
But those you've listed don't sound like that.
A sign might be if an OTC antihistamine helps.
I have MCAS, so have 100s of triggers I have to avoid. Docs for MCAS are only slightly easier to find than for MCS. But I don't get or need any help with it, cos there are many meds for it, but meds usually don't help me.
