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 ulnar nerve is derived from the brachial plexus. It is a continuation of the medial cord, containing fibres from spinal roots C8 and T1. After arising from the brachial plexus, the ulnar nerve descends down the medial side of the upper arm. At the elbow, it passes posterior to the medial epicondyle, entering the forearm.
