Your symptoms and the physical examination may give your doctor enough information to diagnose the problem. However, with back pain, your doctor may only be able to tell you that the problem is not serious. If your doctor determines that your back pain is caused by muscle strain, obesity, pregnancy or another cause that is not urgent, you may not need any additional tests. However, if he or she suspects a more serious problem involving your vertebrae or spinal nerves, especially if your back pain has lasted longer than 12 weeks, you may need one or more of the following tests:

“The less gasoline we burn, the better we’re doing to reduce air pollution and harmful effects of climate change,” Walke says. “Make good choices about transportation. When you can, walk, ride a bike, or take public transportation. For driving, choose cars that get better miles per gallon of gas or choose an electric car.” You can also investigate your power provider options—you may be able to request that your electricity be supplied by wind or solar. Buying your food locally cuts down on the fossil fuels burned in trucking or flying food in from across the country. And perhaps most important, “Support leaders who push for clean air and water and responsible steps on climate change,” Walke says.

For nonexperimental data, causal direction can often be inferred if information about time is available. This is because (according to many, though not all, theories) causes must precede their effects temporally. This can be determined by statistical time series models, for instance, or with a statistical test based on the idea of Granger causality , or by direct experimental manipulation. The use of temporal data can permit statistical tests of a pre-existing theory of causal direction. For instance, our degree of confidence in the direction and nature of causality is much greater when supported by cross-correlations , ARIMA models, or cross-spectral analysis using vector time series data than by cross-sectional data .
