These are the symptoms of Post Traumatic Stress Disorder given on the National Institutes of Mental Health website:

Symptoms of PTSD fall into three main categories:
1. Repeated "reliving" of the event, which disturbs day-to-day activity

• Flashback episodes, where the event seems to be happening again and again
• Recurrent distressing memories of the event
• Repeated dreams of the event
• Physical reactions to situations that remind you of the traumatic event

2. Avoidance

• Emotional "numbing," or feeling as though you don’t care about anything
• Feelings of detachment
• Inability to remember important aspects of the trauma
• Lack of interest in normal activities
• Less expression of moods
• Staying away from places, people, or objects that remind you of the event
• Sense of having no future

3. Arousal

• Difficulty concentrating
• Exaggerated response to things that startle you
• Excess awareness (hypervigilance)
• Irritability or outbursts of anger
• Sleeping difficulties

You also might feel a sense of guilt about the event (including "survivor guilt"), and the following symptoms, which are typical of anxiety, stress, and tension:

• Agitation, or excitability
• Dizziness
• Fainting
• Feeling your heart beat in your chest (palpitations)
• Fever
• Headache
• Paleness

Not every person will experience all of these symptoms so combinations of these will vary from person to person. Treatments vary according to how the symptoms impact the person.

Hope this helps some.
