Some of the (lesser known?) symptoms might include irritability, social anxiety (not wanting to go out in public, avoiding crowded places), self-medicating with alcohol / drugs, emotional withdrawal from friends/family, depression, etc. The symptoms of PTSD are quite similar to those of depression, and also nearly identical to those of POST-CONCUSSION SYNDROME / MILD TRAUMATIC BRAIN INJURY. For example, many of our returning soldiers have sustained both a concussion and are also suffering from PTSD: the symptoms are hard to tease out, though nearly everyone who has gone through a traumatic event - whether it is being injured yourself or seeing others in traumatic situations - will have some degree of PTSD. This does not preclude other existing conditions, such as post-concussion syndrome (fatigue, headache, irritability, inability to concentrate, nausea, scattered thoughts) or other psychological issues (social anxiety, mild depression). One of the hallmarks of PTSD is the "reliving" of the traumatic event, often with no control over obsessing over the details. Feeling as if you are in a heightened "fight or flight" constantly, feeling jumpy at loud noises, bright lights. There is literature on the differences / similarities between PTSD and post-concussion syndrome.
