I'm in agony with my legs so i have to lie down and it takes a hour for the pains to pass as i can't get up while the pains are there is this normal?
Well - it is of course very normal that if we're in agony, that it will take a while of resting for pain to pass, if that helps at all.
And it is normal that rest can help pain. Not necessarily so, but normally so.
It is also normal for fibro that we can be (& are) in agony in certain parts of our body. But that doesn't mean it has to be the fibro. It can just as well be something else.
But whatever it is - being in agony is not normal, there is something wrong with our bodies, fibro or otherwise. Some people might believe as it's normal for fibro we can do nothing about it / just need to accept it. My own personal experience is that I can do something about every single sort of pain that I have by finding triggers & trying out tons of treatments. I've been able to stop 99% of local pains. The debilitating body ache is much more persistent & together with fast exhaustibility (my main sort of fatigue) etc. has permanently brought my activity down to 40%, and that only if I do a lot of things to keep it up that far - and I have tried >100 treatments and at the moment am doing 3-4h of self-treatments every day (some of these parallel and a lot while I am doing other things).
In the case of leg agony making us/me lie down, but getting better after an hour, the first thing I'd look at is
overdoing something, mainly standing and walking.
To overcome it, I first try putting my legs up. When that was tough for me I even did that on walks. I made sure we came to benches or walls on the way, laid down on them. Also everything sunkacola has suggested.
To prevent it, I vary short or long breaks, and these in time, not when it starts hurting. Generally I sit on the floor most of the time, that's best for my back and also legs, I can change positions quickly and do all sorts of stretching exercises. Not on chairs. If at all on bar stools, so I can swivel. If I need to work etc. walking and standing, I need breaks, again sitting on the floor, or at least putting my legs up on some chair etc. Pre-fibro I stood to work. When fibro started I then got local pains in my legs, which I've got rid of thru various kinds of physio. And Ache & fatigue which I can improve a bit with supps. At the moment I've started doing an ambitious exercise called horse stance, for half to one minute, aiming to increase. That shows that my legs are still very strong. I've always cycled and on good days in good hours I still get energy bursts where I can cycle faster than anyone else. But fibro makes doing things longer than a certain time, i.e. stamina, very hard, despite my strength and short-term energy... So I need to keep under 3 minutes, or if I want to go really fast (20mph or more) better one minute. Without any discomfort at all. But if I go over that or at the wrong time, my whole body breaks down completely. I've learnt to judge that.
Some people with fibro (apparently), on youtube, websites and forums, claim we need to "push thru the pain". Like sunkacola I disagree: There are short times when that is fitting, but in the case of agony we need to stop and rest, just as you are doing. Just I'd do it early and in a way that you stick to the sweet spots, under a certain limit. For this if you're like me you may need some kind of alarm to remind you in time. That way you can keep track of how long you can manage without agony building up.
