Denver Chiropractor Dr. Glenn Hyman: Back Pain and Neck Pain are a Major Cause of Missed Work.

An evaluation of data concerning over 8,000 Spanish workers reveals a correlation between chronic neck and back pain, and missing one or more days of work for health-related issues. Individuals who reported having frequent neck and back pain were 44% more likely to be absent from work for more than 30 days out of the year.
