Usually pain in a certain part of your body signals that something in that area needs attention. In fact, this is the how pain benefits us. Being the wise, nonprocrastinating person you are, you tell your family doctor about this. Then, the unexpected (though not entirely unwelcome) occurs: Your doctor performs tests like X-rays or an MRI, only to discover no obvious cause of the mysterious pains you're experiencing.
You may have fibromyalgia, a mysterious condition that results in aches and pains, and affects more women than men. Fibromyalgia seems to result in heightened sensitivity to physical pressure or pain, and often involves sleep difficulties. Currently, no definitive test for fibromyalgia exists, but doctors will work to rule out other possible causes of your pain before making a diagnosis. This condition is treatable with physical therapy and analgesics, but researchers still have much to learn about it.
It's incredible, but depression can also cause "floating," random and otherwise unexplainable pains in various parts of your body. This may manifest in the form of back pain, headaches and heightened sensitivity to pain.
How can this be? It turns out that pain and emotion travel down some of the same neural pathways in your brain. For some people, it seems that neurotransmitters carrying news of gloom and doom can jump the tracks and result in actual physical pain. Usually, antidepressants, therapy or some combination of the two helps to resolve the depression and, with it, the pain.
