What are the main signs and symptoms of hypermobility?

Excessive joint range of motion is the primary sign of hypermobility, but common reasons for seeking medical support include pain, injury, and joint instability. Although the cause is unclear, hypermobility is also associated with increased prevalence of anxiety, fatigue, immune dysfunction, autonomic nervous system dysfunction, sleep disturbances, gastrointestinal problems, and gynecological complications.^[1]
