I get severe body aches when I get depressed. Usually in my back legs and neck. My personal belief is when your down your body picks up on it and goes into a flight state and just in it's own way telling you what you need. When I start aching really badly in a depressive state I speak with my pdoc and see if I need a temporary med adjustment to help my depreion and get me moving. Once I get a little more motivated and move some more the aches start to subside.
