Exercise helps reduce pain from nerve damage caused by injury, diabetes and other conditions, according to a study involving rats.
Researchers found that exercise appears to ease this type of pain -- called neuropathic pain -- by reducing levels of inflammation-causing substances called cytokines.
Neuropathic pain is common but hard to treat. These findings suggest that exercise could provide an effective non-drug treatment for neuropathic pain, according to lead author Yu-Wen Chen, of China Medical University in Taiwan, and colleagues.
