its so random O.O
It may also be a food allergy. keep a journal. Sometimes it can take hours or days for it to show up. But if the day following a pizza with everything on it you find this happens, start eliminating a topping at a time. write everything down.
It might be a chemical reaction to a perfume or a cleaner. does it happen after someone visits?
when it happens, right down everything that you can remember leading up to the event.
Then after many events, re read what you have written and see if there are any commonalities.
be a detective, start by gathering information and then contemplating.
I hope it is easy and you are well.
nothings changed in my life style
i use the same cleaners, shampoos, order from the same pizza place
and i dnt really use perumes too much.
