What type of pain originates from the organs?

Visceral pain is derived from the internal organs, which can include structures such as the heart, lungs, liver, or gastrointestinal tract. It is often more vague and less localized than other types of pain, as it arises from the sensory receptors within the organs. People typically describe this pain as a deep, squeezing, or aching sensation.

In contrast, somatic pain originates from the skin, muscles, and bones and tends to be well localized. Nociceptive pain is a broader category that encompasses pain resulting from the activation of pain receptors due to injury, inflammation, or trauma, which can include both somatic and visceral sources. Chronic pain, while it can be either somatic or visceral in origin, specifically refers to pain that persists over a long period despite the absence of a clear injury or damage. Thus, the classification of visceral pain distinctly addresses the source as being from internal organs.
