Posttraumatic Stress Disorder (PTSD) is a disorder that can occur after you have experienced a traumatic event. PTSD symptoms usually start soon after the traumatic event, but may be delayed several months or years. Symptoms also may come and go over many years. If the symptoms last longer than 4 weeks, cause you great distress, or interfere with your work/home life, you probably have PTSD.
Symptoms of PTSD include reliving the event, avoiding places or things that remind you of the event, a shift to more negative thoughts and feelings, feeling numb, and feeling keyed up (also called hyperarousal).
If you think you have PTSD, it is important to get treatment. There are good treatments available for PTSD — treatment can help you get better.
