    I found this article on the home page and I remember someone had posted a topic wondering if they were the same...I can't remember who, nor can I find the, but here is an article and I hope the person who posted can find this thread!!


    FM and ME/CFS – The Same, Related, or Different?
    by Karen Lee Richards*

    06-23-2008 The question as to whether fibromyalgia and ME/CFS ('chronic fatigue syndrome') are the same illness, closely related illnesses, or completely different illnesses has been debated by physicians and scientists for many years.

    Some feel FM and ME/CFS are different facets of the same illness, while others believe they are distinct disorders that share several common symptoms. To further complicate the situation, 70 percent of people who have been diagnosed with one are also diagnosed with the other.

    A new paradigm put forth several years ago by Muhammad B. Yunus, MD, suggests that FM and ME/CFS, along with a number of other conditions like irritable bowel syndrome, migraines, and multiple chemical sensitivities, are part of a larger group he terms “Central Sensitivity Syndromes.” The uniting factor that all of these illnesses have in common is central sensitization – an exaggerated response of the central nervous system to stimuli.

    Overview of FM and ME/CFS

    Before enumerating their similarities and differences, let’s look at a brief overview of FM and ME/CFS.

    FM – FM (Fibromyalgia) is a malfunction of the central nervous system that causes disordered pain processing, and results in pain amplification. The primary symptoms of FM are:

    Widespread chronic pain
    Extreme fatigue
    Sleep problems.
    Other symptoms that may occur include: allergies, irritable bowel, irritable bladder, headaches, migraines, dizziness, numbness and tingling, sensitivity to cold or heat, depression, restless legs syndrome, chemical or environmental sensitivities, impaired balance or coordination, dry eyes and mouth, vision problems, or problems with memory, concentration and cognitive functioning.

    ME/CFS – ME/CFS (Myalgic Encephalopathy or Myalgic Encephalomyelitis / Chronic Fatigue Syndrome) is an illness characterized by prolonged and debilitating fatigue accompanied by a number of other symptoms, including: memory and concentration problems, recurrent sore throats, unrefreshing sleep, muscle and joint pain, and headaches.

    Generally speaking, ME/CFS includes at least four of the following:

    Post-exertional malaise lasting more than 24 hours
    Non-refreshing sleep
    Short-term memory or concentration problems
    Muscle pain
    Multi-joint pain without joint swelling or redness
    Headaches of a new type, pattern or severity
    Tender cervical or axillary lymph nodes
    Sore throat.
    Over the years, there have been a number of definitions of ME/CFS. The best thus far seems to be the new Canadian Definition. You can download a full copy of the Canadian Definition here (

    Comparing and Contrasting

    While the two illnesses have a number of similarities, they also have some distinct differences.

    Similarities – In addition to some symptom similarities, FM and ME/CFS have several things in common:

    Reduced cerebral blood flow to the cortex and midbrain
    HPA (hypothalamic pituitary axis) suppression
    Reduced levels of serotonin
    Non-restorative sleep
    Reduced levels of growth hormone
    Evidence of a genetic component.
    Differences – Although there are many similarities, there are also significant differences.

    FM is identified by 18 distinct tender points (designated points on the body that are painful when four kilograms of pressure are applied), while ME/CFS is distinguished by post-exertional malaise (deep fatigue and exhaustion following physical exertion, which lasts more than 24 hours).
    Substance P (a neurotransmitter that sends pain signals) is elevated in FM but not in ME/CFS.
    RNaseL (a cellular antiviral enzyme) is frequently elevated in chronic fatigue syndrome but not in fibromyalgia.
    ME/CFS is often triggered by an infectious or flu-like illness, while FM is usually triggered by a severe physical or emotional trauma (for example, injury, illness, surgery, prolonged stress).

    Getting an accurate diagnosis of either disorder can be difficult to say the least.
    People are rarely diagnosed with both at the same time or by the same doctor.
    Even though each illness has its own set of diagnostic criteria, sometimes the diagnosis you receive may depend more on which one your doctor is most familiar with.
    The fact that such a large percentage of patients have both FM and ME/CFS makes it especially difficult to distinguish between them.

    Treatment of both FM and ME/CFS is primarily aimed at relieving symptoms.
    To date two medications have received FDA approval for the treatment of FM.
    No medication has yet been approved for treating ME/CFS, but clinical trials are being conducted with the hope that at least one will be approved soon.
    It is becoming apparent that there are a number of subtypes of ME/CFS, which further complicates the search for effective treatments.
    It’s usually a matter of trial and error for patients with either illness to find an effective treatment plan.
    Most who have had some success in improving symptoms report using a combination of medication, alternative/complementary therapies and lifestyle changes.

    This is a nice article to print and take into a doctor's office.

    The list of symtpoms is concise and comprehensive at the same time. Of course, we all have a few more symtoms but these are the major issues.

    I can say without doubt that when I first got sick, I had CFIDS/ME. Not FMS. Sudden onset viral issues.

    Then when I relapsed in 2003 - I developed FMS due to extreme stress and I had been over-exercising.

    It is striking to me to know the difference.
