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.
Treatment to reduce the pain of postherpetic neuralgia includes: 1  Antidepressant medicines, such as a tricyclic antidepressant (for example, amitriptyline). 2  Topical anesthetics that include benzocaine, which are available in over-the-counter forms that you can apply directly to the skin for pain relief.
