Musculoskeletal disorders are a variety of minor conditions that affect the muscles, bones, and joints.
Although we describe them as minor conditions, the severity of the pain can be very debilitating to the patient and can interfere greatly with everyday activities.
ArthralgiaArthralgia: literally means joint pain and it is a symptom of injury, infection, illness, or an allergic reaction to medication.
Arthritis: a disorder that involves inflammation of one or more joints, with there being over 100 different forms of arthritis. Osteoarthritis is the most common form, with trauma, infection and age being the usual causes. Other forms of arthritis include rheumatoid arthritis, psoriatic arthritis, and related autoimmune diseases. Joint pain is the major complaint and is often constant and localized to the affected joint. The pain can have many causes: inflammation that occurs around the joint, damage to the joint from disease, daily wear and tear, muscle strain that causes forceful movements around stiff and painful joints, and fatigue.
