Yesterday I had a strong "nauseous burning sinus headache", a bit more energy / less pain, and needed to pee every hour at night and half an hour a lot of the day. (A nauseous burning sinus headache is roughly like a noseful of water while swimming, 80% of that. Or drinking water thru the nose (neti) but forgetting the 0,9% salt.)
That symptom combination is now getting clearer to me as all being from a histamine overload.
I was puzzled what from, as I'd been going easy on histamine food - I thought: It was Camembert, which I thought was "young", but mould cheese is "matured" despite being only a few weeks old. (Or is that kind of mould a problem itself, too?)
Weird getting slightly more energy and less pain, but today I have that too. So it might be from being able to get up early again by reducing the antihistamine.
Don't quite get it yet, but at least I now know roughly what to look for.
And very interesting the notion that my bladder problems are maybe also mast cells overreacting. But if so, how come I had that symptom pre-jab, from fibro alone....?
Last night I had overractions to insect bites/stings again, but after a longer sleep break trying various things without any success, I remembered last time I thought I might be able to reduce the histamine build-up with a cold shower, and that didn't decrease the itch directly, but I was still able to get back to deep sleep, almost 7h then, whilst last time without a cold shower I was down to 5h. So I'm glad to be able to cold shower again.
. So warm inside.

- bad for my need of oxygen.
gled it and the picture confirmed) 2nd 1 bit me 3 days ago, I'm becoming a magnet to the insect world (I don't want to be!) I dont mind ladybirds though 
(they're not fun)
