Patients with chronic pain may be more sensitive to pain and other stimuli true or false
Zielflug [23.3K]
<span>This is true<span> as patients that are in chronic pain are sensitive to acute recurrences of pain whether in the same body part or in different areas of the body. While pain is considered a sensation, and sensations are desensitized after prolonged exposure; the opposite is true for pain as people suffereing from chronic pain becomes more sensitive to pain.

</span><span><em>This principle is adapted from the 9 core principles of pain assessment (Lewis's Medical-Surgical Nursing, 2017)</em>
<em>1. Patients have the right to appropriate assessment and management of pain.</em>
<em>2. Pain is always subjective</em>
<em>3. Physiologic and behavioral signs of pain are not sensitive or specific for pain</em>
<em>4. Pain is an unpleasant sensory and emotional experience.</em>
<em>5. Assessment approaches, including tools, must be appropriate for the patient population.</em>
<em>6. Pain can exist even when no physical cause can be found</em>
<em>7. Different patients experience different levels of pain in response to comparable stimuli.</em>
<em>8. Patients with chronic pain may be more sensitive to pain and other stimuli</em>
<em>9. Unrelieved pain has adverse physical and psychologic consequences. Acute pain that is not adequately controlled can result in physiologic changes that increase the likelihood of developing persistent pain.</em></span></span>
