Post-traumatic stress disorder (PTSD) is a severe anxiety disorder that can appear as a delayed response after exposure to any event that results in psychological trauma.
PTSD is less frequent but lasts longer than an acute stress response, which is an immediate reaction to such an event.
Formal diagnostic criteria require that the symptoms last more than one month and cause significant impairment in social, occupational, or other important areas of functioning. In some cases, hypnotherapy has been proven effective.
This magnetic cache should take less than one month to find and may cause you some stress, but there should be no (lasting) trauma involved.
