That sunburn may be painful and annoying, but it also may help the medical community.

FOX's Colleen Cappon reports in today's "Housecall for Health"...

Scientists have found that sunburns could be the key to developing new pain management drugs.

Research from Kings College - London has found a molecule in the body that controls sensitivity to pain from UV-B radiation.  The molecule works by sending inflammatory immune cells to injured tissue, stopping pain and tenderness.

Researchers hope the discovery may help with drugs to ease arthritis and other forms of chronic pain, which costs the U.S. $150 billion a year.
