I too have a painful left leg, worse at night in bed, feels like pins and needles and the heel is a bit 'dead' at times, and it sometimes aches whilst I am sitting down, gets - a bit fidgety, but it seems as soon as I start to do something, the pain disappears. This morning for instance I have been out in the fresh air for 2 hours playing a rather long game of bowls as part of the club competition. It was very hot, which makes a change this year, and I arrived home totally shattered - no leg problem while playing, it's aching again now though, which makes it all a bit confusing.
