Hi ive been getting this sensation for years and noboby seems to know what it is ,ive come on this site to ask about it and find lots of others have it too ,so im not the only one ,i used to think it was eating too much sugar but now i get it all the time ,its hard to sleep with it so i take regular pain killers and then i know i will sleep but i dont want to take painkillers ,some times this sensation travels down my legs to my toes and i cant concentrate on my work as i feel the only bit of relief i get is when im walking sitting down is quite uncomfortable .i also now feel headachy when i get it ,im all up tight and very aggitated ,i am usually a very healthy person but this is getting worse whatever it is ,anybody know what it is yet ? .thank u for allowing me to ask this question .
