Thoracic outlet syndrome is a medical disorder that causes pain, numbness, tingling and weakness in the arms and hands, headaches, chest pain, and neck pain. Thoracic outlet syndrome may also present as a blood clot, aneurysm, or arterial occlusion.
Compression of arteries, veins or nerves causes three types of thoracic outlet syndrome. TOS patients can develop permanent weakness, blood clot, aneurysm, or sudden loss of blood flow to the arm. While thoracic outlet syndrome can cause very serious disease, an experienced thoracic outlet syndrome specialist can speed up accurate diagnosis and treatment of TOS.
