A 35 year old woman complains of widespread pain so debilitating that she has been unable to work for the last several weeks, though she did not experience any significant injury that seems to account for the pain. For example, the patient states that her pain is stimulated by the lightest touch, even when her 3-year-old daughter touches her or hugs her, she cringes due to pain. What type of pain response is this experience indicative of?
Explanation & Rationale
A. Allodynia: Allodynia refers to pain triggered by stimuli that are normally non-painful, such as light touch or gentle pressure. The patient’s description of pain in response to her daughter’s touch exemplifies this abnormal sensory processing. B. Acute pain: Acute pain is typically a short-term response to tissue injury or inflammation. The patient’s chronic, widespread pain without a clear injury does not fit the definition of acute pain. C. Hyperalgesia: Hyperalgesia is an increased sensitivity to stimuli that are normally painful. While related, the patient’s pain occurs with non-painful stimuli, which is more characteristic of allodynia rather than hyperalgesia. D. Neuropathic pain: Neuropathic pain arises from nerve injury or dysfunction and often presents with burning, shooting, or tingling sensations. The patient’s pain is stimulus-dependent and widespread, aligning more with allodynia than classical neuropathic pain.
