1. Joy, a young scientist, was enjoying her career until she began developing chest pains, palpitations, dizziness, and fainting every time she headed to work. Two doctors found nothing wrong and suggested that her chest pains were due to job stress. One even put her on Valium, but she feared that it would interfere with her ability to do her job. She decided to visit a specialist where cardiac testing showed that she had mitral valve prolapse.

2. Sleep disorders, which one out of every four Canadians suffers from, can be life threatening. The good news is that through proper diagnosis and treatment, most sleep disorders can be cured.

Narcolepsy is a kind of sleep disorder which causes daytime sleepiness. This means that a person can fall asleep at any time, very often at a wrong time or place. Cataplexy - another kind of sleep disorder- causes loss of muscle control which can cause a person to collapse. Cataplexy is usually caused by a strong emotion, such as a sudden surprise.

4. For most people, low back problems are caused by muscle tension or spasm, muscle tears, and joint problems. Sometimes nerves from the spinal cord can be upset by "slipped" discs causing buttock or leg pain. This may also cause numbness, tingling, or weakness in the legs. Emotional stress or long periods of inactivity may make back problems worse.
