According to the Children's Hospital of Pittsburgh, RND is an acronym that stands for Reflex Neurovascular Dystrophy. It is a painful condition that affects the joints and muscles of children.
The Children's Hospital of Pittsburgh explains that the pain of RND is caused by nerve sensitivity. Nerve triggers send inappropriate pain signals to the brain, causing distress to victims of the condition. RND typically affects female children, who make up 80 percent of RND cases.
Symptoms of RND include headaches, chest pain, stomach pain, poor concentration, memory loss, dizziness, loss of appetite, fatigue, extended napping and more. Treatment programs at the Children's Hospital of Pittsburgh include exercise therapy and pain reduction techniques.
