The best strategy is to cure the condition before it becomes chronic. This is why the medical system expedites cases that are not yet chronic. See MedicineNet's long definition and discussion of chronic pain. This includes how pain affects men and women differently, neuropathic pain, and nerve blocks. PN pain is neuropathic pain.

For example, the duration of a chronic aquatic toxicity test could be 96 days or more, and mortality is the response usually measured (EPA 1997).
In medicine, a chronic disease is a disease that is long-lasting or recurrent. The term chronic describes the course of the disease, or its rate of onset and development. A chronic course is distinguished from a recurrent course; recurrent diseases relapse repeatedly, with periods of remission in between.
