Symptom #3: Allodynia and Hyperalgesia
Allodynia is a medical term that refers to sensitivity to pain that occurs without non-painful stimulation. Allodynia can be aggravated by stimuli such as temperature or physical stimuli and can provoke a burning sensation. It is different from hyperalgesia which is an exaggerated response to a stimulus that can be painful.
Hyperalgesia is the increased sensitivity to pain that may occur due to the damage of receptors or peripheral nerves. There are two types of hyperalgesia, where the primary form refers to pain occurring in damaged tissues while the secondary form refers to pain that happens in surrounding undamaged tissues. Both are seen in neuropathy and affect 15 to 50% of patients affected by it.
