I have fibromyalgia which I keep mostly under control with daily medication. However, there's obviously flare ups and if I do too much then I suffer then next day or two.
I went out the other night (I was having good pain level evening) and got really pissed off by stupid comments eluding to how I 'couldn't be that bad' as I was out.
The next day I could barely move off the sofa (I was expecting that and had planned for a painful day).
Why don't people understand that just because we look ok on the outside for a few hours doesn't mean that we're fine.
