Hi Cathy and welcome in!
Well, answers to this question about fibromyalgia-flares are very individual, even more individual than what may generally help!
The most common/usual/common ground answer is:
rest and wait, and during that do good things to keep your spirits up, if possible keep up regular short gentle stretches, so further pains due to moving less don't add themselves on.
Another fairly common one is warm baths (or in my case cold showers if I manage) or something like a good magnesium sort.
But to go into more detail there it's necessary to know
what areas your flare affects: overall Ache, local pains, sleep, gut etc.
To put that generally: it's as ever a case of identifying symptoms and triggers, and preventing or alleviating each.
As you are
taking meds it would also be on of the first things to question if your symptoms are triggered by their
side effects.
But you've already consulted sunkacola's general Advice Post
here at the top of the forum I guess?
CBD again is a broad field. We all react so differently to it - in my case a tiny drop of high quality oil zombifies me, not helping.
And there are so many different types that I'd assume it'd be better to test that after the flare, rather than in it.
Sunkacola - away for a few weeks - is a real expert on that and regularly gives recommendations - you could search for CBD-threads (magnifying glass top right of the page) or if you need help I could look up some for you.
As I've been in a full fibro-flare since Dec19, I've needed my toolkit of many kinds of physio, 20-30 supps, a mix of many diets, trigger hunting & symptom analysis etc. just to work & play for at max. 4 hours a day. Any added flare on top of that aside from stopping everything = rest means going thru my complete tool box again if there's anything I can detect & readjust. In some cases Wim Hof's cold showering and/or breath-holding help me - my body is eccentric like that...
