It took me 3 days to recover from 4 hours of work. My arms ached all the way down, my shoulders ached in front and back, my legs ached from hips down to toes and my head and neck ached. I actually felt like I had been run over by a bus. So the idea is to rest but the pain in muscles makes it almost impossible to lie down and relax. So what do you do when you are having one of these days?
