Which one of the following is not a possible symptom of fibromyalgia?

Fibromyalgia is a chronic condition characterized primarily by widespread musculoskeletal pain, along with other symptoms such as fatigue, sleep disturbances, and cognitive difficulties. Common associated symptoms can include headache, depression, and paresthesias (which are abnormal sensations like tingling or numbness).

The symptoms of fibromyalgia do not typically encompass psychosis. Psychosis, which includes delusions and hallucinations, is more indicative of severe mental illnesses such as schizophrenia or severe mood disorders. In contrast, while individuals with fibromyalgia may struggle with mood disorders like depression or anxiety due to the chronic nature of their pain and the impact it has on their overall well-being, these are not psychotic symptoms.

Understanding this distinction is crucial in clinical practice to ensure appropriate diagnosis and treatment, as addressing mood symptoms may be essential for a holistic approach to managing fibromyalgia, whereas treating psychosis would require a different clinical strategy.
