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 radial and ulnar arteries, which are branches of the brachial artery, provide the blood supply to the hand. Supplemental arteries in the forearm include the anterior interosseous artery, the posterior interosseus artery, and (occasionally) the median artery, all of which are branches of the ulnar artery.
