Benign hypermobility describes looseness of joints that may be associated with daytime pain, nighttime awakening or discomfort after exercise.
Patients generally report multiple complaints of pain over a prolonged period.
In the past, this type of general pain often has been called growing pains or limb pain, which can be similar but are different disorders. Children or young adults with hypermobility usually have joint pain or mild swelling during the late afternoon, at night, or after an exercise or activity. The pain is more common in the lower extremities, such as the calf or thigh muscles. The pain most often involves large joints such as the knees or elbows, but can involve any joint. Swelling is not usually present, but when found is due to normal, activity-related trauma to the joints.
