Maybe this is Chronic Fatigue Syndrome.....(part 2 diagnostic testing)

Having to go through test after test and visit expensive specialists only to be told "This is not my field of expertise" was frustrating and exhausting. He had tests to check iron levels etc, white blood cell count and to rule out Thyroid problems, fibromyalgia, anemia, Lyme disease, lupus, MS, hepatitis, sleep disorders and depression. Apparently everyone has to do this......here's a copy of the official info.

Since there is as yet no diagnostic test for identifying CFS or proven physical marker for the illness, diagnosing CFS can be difficult. Severe fatigue and other symptoms of CFS can be caused by several different illnesses. The following criteria were developed in 1994 by an international consensus committee organized by the US Centers for Disease Control. Using their guidelines, CFS is diagnosed in a two-step process. Doctors use the list below to diagnose chronic fatigue after all other tests are negative. The patient must display both 1 and 2.

1. At least several months (most doctors say 6 months) of a new, debilitating fatigue (severe to moderate) that forces a substantial reduction of activity (50% - 85%).

2. Four or more of the following eight symptoms:
* Impaired memory or concentration (mental confusion)
* Sore throat
* Tender lymph nodes in the neck or armpit
* Muscle pain
* Joint pain without redness or swelling
* Headaches of a new or different type
* Non-restorative sleep
* Extreme fatigue following activity (“post-exertional malaise”)
