You'll see yellow lights shining in the Marquette Interchange this weekend, but why?

MILWAUKEE (WITI) -- In conjunction with "Pain Awareness Month" in Wisconsin, the southwest pier system corridor of the Marquette Interchange will be up-lit with yellow beginning Friday, September 26th through Sunday, September 28th.

Yellow is the official color of a national effort to increase the awareness of pain, which is the primary cause of lost workdays in the U.S.

Advanced Pain Management, the Wisconsin chapter of the American Society for Pain Management Nursing and the American Chronic Pain Association (ACPA) joined efforts to receive an official proclamation from Governor Scott Walker to declare September as Pain Awareness Month in Wisconsin.

Advanced Pain Management and other organizations are conducting a #GoYellow campaign to raise awareness about pain, which affects nearly 100 million Americans – more than cancer, heart disease and diabetes combined.

Advanced Pain Management is one of the largest pain management groups in the country, with more than 30 board-certified/eligible physicians offering the most advanced techniques for pain control. Advanced Pain Management physicians operate out of more than 40 locations in Wisconsin, including metro Milwaukee, the greater Madison area, Racine, Sheboygan, Green Bay, Wausau, as well as in Mankato, Minn.
