Effectively treating chronic pain will require a broad culture shift in medical care and research, a panel of experts said at a AAAS event.

Researchers at the 2015 AAAS Annual meeting said more studies are needed to understand the best dosing and delivery methods for medical use.

Researchers have discovered a molecule responsible for triggering the inflammatory pain of sunburn caused by the sun’s UVB rays, reports a new study in the 6 July issue of Science Translational Medicine.

The molecule—part of a family of proteins called chemokines—works by activating nerve fibers to cause pain and tenderness. The findings could lead to drugs that block the activity of this molecule, called CXCL5, to reduce or stop pain in sunburned skin.
