Have you tried the hot bath thing, and maybe wearing a different pair of comfy shoes? (Sorry, the aching legs and feet thing is the only one I know anything to help with.) I can promise that gets better.
I'm definitely changing shoes tomorrow. I may look like an idiot but no one is really going to see my feet.
I might have to invest in some knee braces and whip out my ankle braces. Tomorrow I think I'm going to buy some bubble bath and just chill a hot bubble bath after work for about an hour before I do anything else.
