Part 2 of 8 - Pain Is A Symptom of Many Diseases

Arthritis / Rheumatic Conditions

Pain often accompanies disease of the bones, muscles, joints, and skin, which affect millions of Americans. Most of these diseases are chronic and may cause lifelong pain. In certain cases, such as with some rheumatic diseases, the sources of pain may include:

  • inflammation of the synovial membrane (tissue that lines the joints)
  • inflammation of the tendons
  • inflammation of the ligaments
  • muscle strain
  • muscle fatigue

A combination of these factors contributes to the intensity of the pain.

    Muscle Inflammation

    Muscle inflammation characterizes other painful disorders such as:

    • polymyositis (characterized by inflamed and tender muscles throughout the body, particularly those of the shoulder and hip)
    • dermatomyositis (characterized by patchy red rashes around the knuckles, eyes, and other parts of the body, along with chronic inflammation of the muscles)

    Sometimes The Cause Of Pain Is Unknown

    In other cases, such as with fibromyalgia syndrome, the cause of the pain is unknown. A distinct characteristic of fibromyalgia is pain and tenderness in sensitive areas known as tender points. These tender points are distinct from trigger points as seen in other pain syndromes.

    It is important to consult with a physician to help determine the cause and treatment for your pain.
