Disease Database Drug Database Alt. There are pain syndromes like fibromyalgia and arthritis-related disorders, such as systemic lupus erythematosus, that involve every part of the body. True, many older people do have arthritis, but it's not just a disease of the old. Some forms of arthritis affect children still in diapers, while thousands of people are stricken in the prime of their lives. Often that pain is a result of inflammation of the joint lining.
Inflammation is involved in many forms of arthritis.
It is the body's natural response to injury. The warning signs that inflammation presents are redness, swelling, heat and pain. These are the same kinds of reaction the body has to a sliver in the hand, for example. When a joint becomes inflamed, it may get any or all of these symptoms. This can prevent the normal use of the joint and therefore it can cause the loss of function of that joint.
