Pain resulting from tissue injury is classified as which type of pain?

The correct classification of pain resulting from tissue injury is acute pain. Acute pain is typically characterized by a sudden onset and is directly related to a specific injury or health condition. It serves as a warning sign that something is wrong in the body and prompts immediate attention and response. This type of pain usually resolves once the underlying cause, such as a wound or illness, is treated or healed.

In contrast, the other classifications of pain describe different characteristics:

• Pathologic pain refers more broadly to pain arising from dysfunction of the nervous system rather than directly from tissue injury itself. It may not resolve even after the injury heals and can persist as a result of altered pain processing.

• Chronic pain persists for an extended period, often defined as lasting longer than three to six months, and may result from ongoing conditions or can arise from previous acute injuries.

• Neuropathic pain is due to damage or dysfunction in the nervous system itself, often resulting from conditions like diabetes or post-surgical complications, and is characterized by symptoms such as burning or tingling sensations.

Thus, the classification of pain resulting from tissue injury is specifically acute pain, as it signals immediate harm and necessitates prompt treatment.
