Face

Facial pain, like any other pain, is an unpleasant sensory and emotional experience. The term is used to describe, on looking at the face, facial pain before a pain condition is diagnosed. X-ray of the face may show opacification of the sinus or mastoid area. Facial swelling is a common clinical paediatric problem. The term refers to an enlargement of any area of the face, including the eyes, nose, mouth, forehead, cheeks and chin. Swelling is usually caused by an abnormal buildup of fluid in the face – oedema – which is the most common cause of facial swelling. Genuine oedema needs to be differentiated from ‘puffy face’, which is often found in association with obesity, hypothyroidism and Cushing's syndrome. Facial masses are the second most common causes of facial swelling. The appearance of macules or patches does not commonly remain static, and acute eruption can change rapidly to become elevated or blistering.
