PTSD Symptoms and Treatment: When the Past Won't Stay in the Past
A car backfires and you are on the floor before you know it. A certain song comes on at the grocery store and your whole body goes cold. You startle at small things, sleep in short shifts, and keep a quiet watch on every exit in the room. You tell yourself it was a long time ago, that other people had it worse, that you should be over it by now. Yet your body keeps behaving as if the danger never ended. If that sounds familiar, you may be dealing with PTSD symptoms, and I want you to know that this is a normal response to an abnormal event, and that effective PTSD treatment exists.
I'm Dr. Matthew McKeithan, a licensed clinical psychologist who has spent 15 years working with trauma, including with first responders, veterans, and survivors of many kinds of experiences. In this article I'll explain what PTSD is, the main symptoms, how it differs from ordinary stress, which treatments have the strongest evidence, and when to reach out. If you are in San Francisco or the Bay Area and looking for trauma therapy by secure video, I'll cover that too.
Key takeaways
PTSD can develop after experiencing or witnessing a life-threatening or deeply distressing event, and it is more common than many people realize.
Symptoms fall into four groups: re-experiencing, avoidance, negative changes in thinking and mood, and being on high alert.
Trauma-focused therapies such as cognitive processing therapy, prolonged exposure, and EMDR have strong or growing evidence.
PTSD is not a weakness or a character flaw. It is a nervous system that learned to survive.
If symptoms last more than a month or interfere with your life, professional support can make a major difference.
What is PTSD?
Post-traumatic stress disorder is a mental health condition that can develop after a person experiences or witnesses a traumatic event, such as combat, a serious accident, assault, disaster, sudden loss, or repeated exposure to disturbing situations at work. Many people feel shaken after trauma, and most recover over time. PTSD is diagnosed when symptoms persist, typically for more than a month, and interfere with daily life.
According to the U.S. Department of Veterans Affairs National Center for PTSD, about 6 out of every 100 people will experience PTSD at some point in their lives. It is not limited to military service. It affects people from every background, including survivors of childhood experiences, medical emergencies, violence, and accidents.
The four groups of PTSD symptoms
Clinicians look for symptoms in four areas:
Intrusion (re-experiencing): unwanted memories, nightmares, flashbacks, or intense distress when reminded of the event.
Avoidance: steering clear of people, places, conversations, or thoughts that bring the trauma to mind.
Negative changes in thinking and mood: persistent guilt, shame, or blame; feeling detached or numb; losing interest in things you used to enjoy; feeling that the world is unsafe.
Arousal and reactivity: being easily startled, irritable, constantly on guard, having trouble sleeping or concentrating, or acting recklessly.
You do not need to have every symptom to benefit from help. And only a licensed professional can diagnose PTSD, so think of this list as a map, not a verdict.
Why it happens: a body that learned to survive
During a threatening experience, the brain's survival circuits take over. The heart races, muscles tense, and the thinking, reflective part of the brain steps back. In many cases, once the danger passes, the system settles down. With PTSD, the alarm stays stuck in the on position. The memory is stored as if it is still unfolding, and reminders can trigger the same full-body response.
That is why "just forget it" or "think positive" rarely works. The problem is not a lack of willpower. It is a nervous system doing what it was built to do, in a situation that no longer requires it. Understanding that can be a huge relief, because it reframes symptoms as understandable reactions rather than signs that something is wrong with you.
PTSD, acute stress, and complex trauma
Not all post-trauma reactions are PTSD. Acute stress reactions in the first month are common and often fade. Some people experience what is often called complex trauma after prolonged or repeated experiences, especially in childhood or in relationships where they were not safe. This can involve difficulty regulating emotions, a shaky sense of self, and trouble trusting others, in addition to classic PTSD symptoms.
The distinctions matter because they shape treatment. Complex trauma often calls for a slower, more stabilizing approach, with more emphasis on building safety and skills before processing memories. I tailor the pace to the person rather than following a script.
What the research says about PTSD treatment
The American Psychological Association's clinical practice guideline for PTSD strongly recommends several trauma-focused psychotherapies, including cognitive behavioral therapy, cognitive processing therapy, cognitive therapy, and prolonged exposure. It conditionally recommends others, including EMDR. The World Health Organization also recommends trauma-focused cognitive behavioral therapy and EMDR.
In plain terms, the treatments with the best evidence share a common feature: they help you gradually and safely face the trauma memory and the beliefs it created, rather than avoiding them. Medication, particularly certain antidepressants, can also help some people, and that decision belongs with a medical prescriber.
How trauma therapy works
Good trauma therapy usually unfolds in stages. First comes stabilization: building safety, coping skills, and trust. Then comes processing: working with the memory and its meaning, using approaches such as EMDR, cognitive processing therapy, or exposure-based methods. Finally comes integration: rebuilding relationships, routines, and a sense of future.
I often add somatic tools throughout, because trauma lives in the body. Learning to notice sensations, ground yourself, and let the nervous system settle makes the processing work smoother. For a closer look at my approach, you can read about trauma therapy at Your Kind of Happy.
Nothing human is alien
Over the years I have noticed something that happens in nearly every trauma case. At some point, a person says, quietly, "I thought I was going crazy." They had been carrying a private fear that their reactions meant they were broken. When I explain that these reactions are common and make sense, I often see their shoulders drop an inch. It is one of the most meaningful moments in this work.
The Roman playwright Terence wrote, "I am human, and nothing human is alien to me." I think of that line often. Whatever you have been through, and however you have reacted, you are not alone, and you are not beyond help.
When to get help
Consider reaching out to a licensed professional if you notice:
Symptoms that last more than a month after a traumatic event.
Nightmares, flashbacks, or intrusive memories that disrupt daily life.
Avoiding more and more of your life to stay away from reminders.
Using alcohol, drugs, or risky behavior to cope.
Feeling numb, hopeless, or disconnected from the people you love.
Problems at work or in relationships linked to irritability, anger, or withdrawal.
If you are having thoughts of harming yourself, please call or text 988 right away. Veterans can press 1 after dialing 988 to reach the Veterans Crisis Line.
How loved ones can help
If someone you love is struggling, patience and consistency matter more than perfect words. You can listen without trying to fix, avoid pushing them to talk before they are ready, respect their need for predictability, and gently encourage professional support. Looking after your own well-being matters, too. Living with someone with PTSD can be draining, and family members sometimes benefit from support of their own.
Please avoid saying things like "you should be over it by now" or "others have had it worse." Recovery does not follow a deadline, and comparison tends to deepen shame.
Trauma therapy by secure video for San Francisco and the Bay Area
If you live in San Francisco, the thought of sitting in a waiting room or traveling across the city for a trauma appointment may feel like too much on its own. Secure video lets you attend sessions from a space where you feel safe, and it can make showing up consistently much easier.
A systematic review by Greenwood and colleagues found comparable outcomes between video-based and in-person psychotherapy for the conditions it examined, although PTSD specifically was not its focus. Video is not right for every situation, particularly when safety is a concern, and we would discuss that together before beginning.
What you can try this week
Ground yourself. When you feel triggered, name five things you can see and feel your feet on the floor.
Keep a simple routine. Regular sleep, meals, and movement give your nervous system predictable anchors.
Limit numbing. Notice if alcohol or constant screens are a way to escape. A little awareness goes a long way.
Connect. Spend time with one person who feels safe.
Reach out. You do not have to be in crisis to ask for help.
These are starting points. Trauma recovery is real, and the right support can help you reclaim your sleep, your relationships, and your sense of safety.
