New York City-based Columbia University Medical Center researchers investigated the underlying causes of chronic pain, according to AANS Neurosurgeon.
Here are four insights:
1. Researchers studied rodents to discover pain receptors buried in the cells of nerves may be to blame for chronic pain.
2. Chronic pain may be due to pain receptors migrating from the surface of nerve cells to deep inside the cells.
3. Pain medication can't reach the hidden pain receptors hidden within the cells.
4. This discovery may yield the development of new chronic pain medication that is stronger and cases fewer side effects.
