Service members are subject to extreme physical injury and mental stress.  Wounded soldiers often experience substantial pain, which must be addressed before returning to active duty or civilian life. Pain represents a serious and widespread problem both over the short term for wounded soldiers on the battlefield and during rehabilitation, and over the long term for many veterans. The prevalence of certain conditions associated with the development of chronic pain, including traumatic brain injury and post-traumatic stress disorder (PTSD), is higher among military veterans than among the general civilian population. PTSD is a condition in which individuals feel anxiety and panic when reminded of a traumatic event.
