Branches of the trigeminal nerve run through the mucous membranes in your nose here. These become inflamed, causing pain and swelling in the mucous membranes.

The swollen and inflamed trigeminal nerve emerges from your eye socket. This leads to a feeling of pressure in or behind your eyes.

The irritated nerves run directly under the skin here. Applying pressure to the nerves gives you temporary relief.

The two nerves run through the corrugator muscle here. Muscle tension irritates these nerves, causing pain.

This nerve passes through the temporal muscle at the outer rim of the eye socket. Finger pressure on this nerve can give you temporary relief here too.

The pulsating temporal artery is thickened. Applying pressure to this artery can give you temporary pain relief.

Occipital nerve irritation is involved together with the trigeminal nerve as previously described. This causes tension in your neck muscles.

The occipital nerve passes through the trapezius and semispinalis muscles here. The nerve crosses over the artery and causes pain at two points.
