Yeah, that's pretty much the reply I get to any physical problem that doesn't have an obvious cause "it is your depression". I always wonder what the docs say to people who aren't depressed, do they write off symptoms that they can't explain or are not interested in quite so glibly?

As cause and effect go, leg pain could be due to neurotransmiiter imbalance and as neurotransmitters are thought by many to play a role in depression, leg pain really might be down to depression. I guess we should both ask our doctors for a clearer explanation.
