Multiple sclerosis (MS) is an autoimmune disease where the body's immune system attacks the body’s myelin, the protective sheath that encases the nerves in the brain and spinal cord, eventually causing deterioration of the nerves themselves. When myelin is damaged, the messages that travel along that nerve may be slowed or blocked, interfering with the communication between the brain and the rest of the body.
Fibromyalgia is a chronic condition characterized by a constant dull pain throughout the body accompanied by fatigue and sleep disturbances.

Fatigue is a feeling that most of us have probably experienced at one time or another. Whether from stress, poor eating habits, sleep deprivation, overwork, or even medical treatments, fatigue often has a lot to do with our habits and routines, though it can sometimes be caused by an underlying medical condition. But sometimes in spite of what we do, fatigue can become an ongoing problem. In severe cases, it may be diagnosed as chronic fatigue syndrome, a complicated disorder without obvious onset or causes.

Insomnia can cause daytime fatigue or sleepiness, as well as irritability, depression or anxiety, a loss in concentration and focus on tasks, increased errors or accidents, tension headaches and gastro-intestinal problems.
Headaches are a common ailment and can make life very difficult. Headaches can have a wide range of causes, but often the causes are not well understood by Western medicine, and in most cases do not have an identifiable underlying physical cause.

Medications are usually the standard treatment method, however some chronic daily headaches are resistant to all medications.
