Back Pain, Headaches and Asthma

A study conducted on close to 10,000 twins aged 12 to 22 found associations between low back pain and asthma and headache/migraine. The presence of asthma and headache/migraine increased the probability of low back pain considerably more than the presence of only one other disorder. Researchers were not sure why these conditions were related and recommended further study to help explain their findings.
