These conditions include: * Joint instability causing frequent sprains, tendinitis, or bursitis when doing activities that would not affect others * Joint pain * Early-onset osteoarthritis (as early as during teen years) * Subluxations or dislocations, especially in the shoulder (severe limits on one’s ability to push, pull, grasp, finger, reach, etc., is considered a disability by the US Social Security Administration) * Knee pain * Fatigue, even after short periods of exercise * Back pain, prolapsed discs or spondylolisthesis * Joints that make clicking noises (also a symptom of osteoarthritis) * Susceptibility to whiplash * Temporomandibular Joint Syndrome also known as TMD * Increased nerve compression disorders (such as carpal tunnel syndrome) * The ability of finger locking * Poor response to anaesthetic or pain medication * "Growing pains" as described in children in late afternoon or night Associated conditions Those with hypermobile joints are more likely to have fibromyalgia, mitral valve prolapse, and anxiety disorders such as panic disorder.
