Accurate weather forecasts allow us to prepare for rain, snow, and temperature changes. We can avoid driving on icy roads, pack an umbrella, or purchase sunblock, depending on what is predicted. Forecasting also generates information trustworthy enough to evacuate a city at risk from a category 4 hurricane. Meteorology has come a long way; today satellite data inform sophisticated computer weather models. Unfortunately, the same can’t be said for forecasting chronic pain. In most cases, health care providers can’t anticipate early or accurately enough which patients might develop long-lasting pain.
