Cervicogenic Headache
Cervicogenic (say: SUR-vico jen-IK) headache is not a single disorder. It means that the source of headache is a problem in the neck. This can come from a wide range of other causes, from traumatic injury to arthritis. The International Headache Society is responsible for classifying headaches and deciding what to call them.

Chronic Fatigue Syndrome or Myalgic Encephalomyelitis
Chronic Fatigue Syndrome and Myalgic Enchephalomyelitis (say: my-AL-jic en-sef-uh-loh-may-ug-LAHY-tis) are terms used in place of each other. In Canada, this complex, often debilitating medical disorder is known as ME/CFS. In 2003, Health Canada wrote a clinical case definition of ME/CFS. It is: “an acquired illness that affects all body systems, predominantly (mostly) the neurological, endocrine, and immune systems.

Chronic Pelvic Pain in Men
Chronic pelvic pain is the most common reason for men under 50 to visit a urologist. Yet it is very poorly understood. Doctors have called it prostatitis (say: pros-tuh-TIE-tis) for many years, mainly because when the doctor does the exam on a man with this condition, the prostate is very tender. “-itis” means inflammation.

Cluster Headache
Cluster (say: KLUHS-ter) headache is less common than migraine or tension-type headache. It occurrs in about 1 in 1,000 people. Men are much more likely than women to have cluster headaches. The term cluster refers to the fact that the headaches, while brief, occur in clusters of several headaches per day, often at around the same time.

Complex Regional Pain Syndrome
Complex regional pain syndrome (CRPS) is a disorder that was known before as Reflex Sympathetic Dystrophy (say: ree-FLEKS sim-puh-THET-ik DIS-truh-fee). It has also been known by many other names, since it was first described by surgeons during the American Civil War.
