Which condition is NOT associated with neuropathic pain?

Osteoarthritis is primarily characterized by joint degeneration and inflammation, leading to nociceptive pain that arises from structural damage to joints. This type of pain stems from the activation of pain receptors due to tissue injury and inflammation, rather than dysregulation or damage to the nervous system itself, which is a hallmark of neuropathic pain.

In contrast, conditions like spinal cord injury, HIV-related neuropathic pain, and diabetic neuropathy involve direct injury or dysfunction of the nervous system, leading to neuropathic pain. These conditions represent scenarios where nerve fibers are damaged, leading to abnormal processing of pain signals in the nervous system. Therefore, osteoarthritis is not associated with neuropathic pain, making it the correct choice in this context.
