A rheumatologist generally diagnoses fibromyalgia when a patient presents with a history of pain that affects all quadrants of the body for a period of three months. The examination also needs to show a pain response from digital pressure in at least 11 out of 18 allogenic \u201ctender\u201d points. Fibromyalgia is characterized by widespread musculoskeletal pain, difficulty sleeping, mood swings, and memory issues. This condition affects the productivity of patients' lives, including their careers and relationships. Different treatments for fibromyalgia exist, including medications like anti-depressants and counseling. Unfortunately, these treatments are only partially effective. However, clinical trials in the past decade have shown that patients respond to hyperbaric oxygen therapy (HBOT) for fibromyalgia.
