Costoclavicular syndrome, also known as thoracic outlet syndrome, is a condition that occurs when the nerves or blood vessels that pass between the collarbone (clavicle) and the first rib become compressed or pinched. This can cause a range of symptoms in the arms and hands.
Costo-clavicular syndrome (CCS) is a medical condition that occurs when there is inflammation or irritation of the joint where the collarbone (clavicle) meets the breastbone (sternum) in the chest. Treatment for CCS generally involves a combination of self-care measures, physical therapy, and medications. In some cases, surgery may be necessary.
