Many studies link fibromyalgia and depression. In fact, about three out of every 10 people with fibromyalgia also have major depression at the time of their diagnosis.
Some researchers feel that depression leads to changes in brain chemistry. Others look at abnormalities of the sympathetic nervous system -- the part of the nervous system that determines how you handle stress and emergencies. These abnormalities, they contend, may lead to the release of substances that cause more sensitivity to pain...
Here's a look at the common ways that fibromyalgia can be misdiagnosed.
The main symptom of fibromyalgia is widespread pain. You can have pain on the right and left side of the body. It can also be above and below the waist. But the pain may also occur in only one or two places in the body, especially the neck and shoulders.
A diagnosis of fibromyalgia can be tricky because fibromyalgia isn't the only condition with widespread pain.
Besides pain, another major symptom of fibromyalgia is chronic fatigue. But patients with other conditions also have chronic fatigue.
There are other symptoms that may occur in fibromyalgia. But just like pain and fatigue, the symptoms are experienced by patients with other conditions. These symptoms include:
Any combination of these symptoms can also suggest the presence of other serious illnesses, such as:
Another reason fibromyalgia is hard to diagnose is the tendency for groups of symptoms to occur together in fibromyalgia patients. But the groups will not be the same for everyone. So, not everyone with fibromyalgia will have all the symptoms described above.
And because the symptoms can suggest multiple diseases, doctors need to rule them out first as they look for an explanation.
Another problem with diagnosing fibromyalgia is that a patient could have other conditions at the same time as fibromyalgia.
Sometimes health professionals, especially those unfamiliar with fibromyalgia, limit themselves to treating one disease and do not check whether fibromyalgia could be contributing to the symptoms.
Fibromyalgia is usually diagnosed by physical exam. People with fibromyalgia have a history of widespread pain with no evident cause that lasts three months or more. There are usually multiple tender points on the patient's body that are identified by applying pressure to these spots.
There is a blood test to help diagnose fibromyalgia. The test -- called FM/a -- identifies markers produced by immune system blood cells in people with fibromyalgia. Ask your doctor if the FM/a test is right for you.
Getting a Diagnosis of Fibromyalgia
There are several important things to keep in mind when thinking about chronic, widespread pain:
Ongoing chronic pain that is widespread is not in your head. Pain is real and needs to be evaluated.
Keeping a journal of your pain symptoms will make it easier to talk with your doctor about the pain. It will help make sure the doctor has the information needed to properly evaluate your condition.
Consultation with a pain specialist (usually a rheumatologist) who is familiar with fibromyalgia can help diagnose or rule out fibromyalgia as a cause of the pain.
There are effective treatments for fibromyalgia that can reverse the debilitating effect of the pain and greatly improve a person's quality of life.
