1 Deep and constant pain in the cheekbones, forehead or bridge of the nose.  The pain usually intensifies with sudden head movement or straining and usually occurs with other sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever, and facial swelling.
The radial artery is a continuation of the brachial artery and is one of the major blood supplying vessels to the structures of the forearm. The brachial artery terminates at the cubital fossa where it bifurcates into the ulnar artery and a smaller radial artery.
The flexor retinaculum is continuous with the palmar carpal ligament, and deeper with the palmar aponeurosis. The ulnar artery and ulnar nerve, and the cutaneous branches of the median and ulnar nerves, pass on top of the flexor retinaculum. On the radial side of the retinaculum is the tendon of the flexor carpi radialis, which lies in the groove on the greater multangular between the attachments of the ligament to the bone.
