Time for bed, maybe

Sometimes that can be the cause of what you describe.

also I use magnesium spray on my legs helps a lot. 

Try not to take anrihistimines they can also cause leg pain at night.

also apply heat and make a paste from asprin and apply to legs with a cream. Also voltaren cream RX helps with muscles cramps of all types.

if you can get up and do,leg stretched they help the leg cramps pass quickly. 

i know that deep beating thrombosis is another cause and medication from the d can help.

please see your dr ASAP. 

I am concerned about what is causing leg cramps or restless leg syndrome for you. It could be serious or simply muscle cramps. 

Hi Rachel;  I have read the other reply, and agree with most of what is said; however, please don't be too alarmed re seeing doctor.....the only reason you should be concerned re ?a DVT is if you have a painful, swollen calf....(I think that is what "hope for cure" is saying).    For relief with my restless leg syndrome (and most Fibro sufferers complain of this problem, and the sleepless nights, too), I wear TED stockings to bed . These can be bought at any chemist (and some physios)....they  are the stockings that are given to all inpatients in hospitals....they increase the circulation of blood to our muscles.  I also supplement with taking extra Magnesium, via tablet form, and do also rub my muscles with a linament.  Also as I have had this condition for many years, I also find that half a valium (2.5mgms) of a night is very helpful. (this also helps with other muscle spasms/tension/tightness  too, which we all complain of)..however, you may find that your GP may not be too willing to prescribe this, but with a Rhuematologist's okaying same, may help??? I do hope that this helps.....

?Another issue re sleep problems that may arise, is Sleep Deprivation in itself.......I have  experimented with taking Melatonin Supplements (but need to be of a particular brand, as not all work as well): others have started drinking Cherry Juice, as this is high in Melatonin (I like to buy cherries, themselves, when in  the stores/shops).....research has found that Fibro Sufferers are lacking in Melatonin, (the ingredient/hormone  that takes us through the REM stage of sleep, which gives normal restorative sleep), hence why many wake up feeling Brain Fog......try some and see if this helps with your sleep....................wishing you well on your journey.....Bron
