Somatic symptom disorder (SSD) occurs when a person feels extreme, exaggerated anxiety about physical symptoms. The person has such intense thoughts, feelings, and behaviors related to the symptoms, that they feel they cannot do some of the activities of daily life. They may believe routine medical problems are life threatening. This anxiety may not improve despite normal test results and reassurance from the health care provider.

A person with SSD is not faking their symptoms. The pain and other problems are real. They may be caused by a medical problem. Often, no physical cause can be found. However, it is the extreme reaction and behaviors about the symptoms that are the main problem.
