To be honest, I have only been to the G.P twice in the 9 years so maybe thats why there have been no further investigations, the first time was just after I had my daughter and the G.P just said it would go away, I didnt bother going back because I didnt want to make a fuss, but I had to in the last month because the lack of sleep was really getting to me this time the G.P said it was restless leg syndrome but like I said he didnt even look at my legs infact he diagnosed then flexed and extended my knee and confirmed diagnosis.. which didnt give me alot of faith in the diagnosis to be honest. Steve's post has made me think alot about it and it all fits, I ran up and down the stairs 20 times! last night and I did sleep better so thankyou.
Additional Comment I forgot:
No, no symptoms with weight bearing only when I take the weight off my legs I start to feel the pain, weight bearing seems to ease it.
