This session will introduce the general structure and function of the biological macromolecules: lipids, carbohydrates, and nucleic acids. Learning Objectives. 1  To understand the general structure and properties of lipids and phospholipids and their function in the cell.
Postherpetic neuralgia is a nerve pain due to damage caused by the varicella zoster virus. Typically, the neuralgia is confined to a dermatomic area of the skin, and follows an outbreak of herpes zoster (commonly known as shingles) in that same dermatomic area.
Pain associated with post-herpetic neuralgia (PHN) can be very intense, often described by patients as deep, aching and unbearable. In some cases, even a light touch, like the pressure of a shirt or gust of wind, can cause intense pain.
