Has anyone else woken up in the morning with really sore legs? When I woke up today my calves were really sore, but not a cramping sore, but more of the feeling you get when you've done heaps of exercise, and then get a lactic acid build up. I would understand if I had done some exercise, but all I did yesterday was potter around the house - and did a fair bit of sitting... I have had problems with pitting oedema in my feet and calves (they were HUGE yesterday), but not sure if this is related?
