Diseases Marked by Widespread Pain Can Lead to Fibromyalgia, Large Study Finds
People with rheumatoid arthritis (RA), endometriosis and inflammatory bowel disease (IBD) are at greater risk of developing fibromyalgia or chronic and widespread pain later in life, a population-based study in Sweden suggests. The data are consistent with the central sensitization phenomena caused by these diseases, leading to onset of fibromyalgia and chronic pain, and highlight the need for pain itself to be a clinical focus in people with such conditions. The study, "A diagnosis of rheumatoid arthritis, endometriosis or IBD is associated with later onset of fibromyalgia and chronic widespread pain," was published in the European Journal of Pain. Widespread, long-lasting pain is a common symptom of several chronic diseases. Scientists suspect these pain episodes alter the way a person's central nervous system — the brain and spinal cord — perceives pain.
