I call it a flare because that's what it is , out of nowhere the pain intensifies or flares up and you can actually feel it ramping up. It gets to a level that's so high for me , I can't get comfortable, I can think for the high pain level, my body burns with a searing pain from top to bottom, my pressure points become inflamed, I can't bear to be touched , sounds light and smells bother me. Now not everyone's is the same but that's my definition of " flare up !"

I call it a crash, other may call it a flare . When this happens I feel like I've been hit by a bus! The muscle pain and bone ache in my legs is so bad, it's like a heavy weight is on my whole body. The overwhelming fatigue is just as bad as the the pain and I end up bed or sofa bound. This is pretty much how I was first 4 months , however I am glad to
Say not every day now. I crash when I've done just a little to much then I've realised and it will hit me the next day. The positive is it is only lasting a few days now as opposed to weeks or months! I'm a positive person on the whole, but when I crash I find it hard to maintain this due to the pain and fatigue. However, when I feel bit better I resume to my positive nature! Onward and upwards :)

Hope your crashes have become less frequent now x

if its fatigue and it hits like your body has just hit a brick wall? i think crash is a good description... but pain... i personally call it a flare if the pain hits hard.. harder than normal, as theres pain all the time...

Yes but I refer to it as hitting the wall, at that point I have nothing let to give I could just crumble to the floor. I hate that feeling and it comes on so fast

IF iam active to much i crash for couple days and start over again
