Somatic pain is characterized by which pattern?

• A. It follows dermatomal patterns and is well localized
• B. It arises from viscera
• C. It is diffuse and poorly localized
• D. It is only felt in muscles

Answer: (A)

Somatic pain comes from the body's outer structures—skin, muscles, joints, bones, and fascia. It is typically sharp, well localized, and easy to point to. This clear localization happens because these tissues are supplied by specific spinal nerve segments, so the pain tends to map to a defined dermatomal area where that nerve travels. In contrast, visceral pain from internal organs is usually diffuse and poorly localized, since organ innervation is less precise and pain can be referred to distant sites. Somatic pain also isn’t limited to muscles; it includes skin and other somatic tissues, which is why the sharp, well-defined pattern is the hallmark.
