One traumatic event does not even necessarily mean you need treatment for PTSD (and in fact, for many people unless it's something seriously traumatizing one event won't result in anything like that; people are generally pretty good at bouncing back from lesser, isolated trauma in most cases). Of course if you started to suffer issues related to that then you would definitely want to go see someone about it, but in the vast majority of cases being mugged and getting out of it with (relatively compared to the potential) small losses is not going to result in something that necessitates serious (and potentially expensive) treatment. In short, unless you start to suffer symptoms there's no reason to spend money seeking out treatment that you likely won't need. Think of it like any other doctor visit; if you have a deep cut or something you think might get infected, then go see a doctor, and if you have anything that might need their expertise go see one, but all going to see a doctor for a small scrape is going to do is waste your money on treatment that doesn't really provide any benefit that time itself wouldn't (again, personal tolerances may vary; some people can go through hell and come out pretty much unbent, while others break with a whisper, and there is no shame in either). To reiterate: if you feel fine, and you don't notice any ill effects psychologically afterwards, then you are probably fine. If you don't feel fine, or you notice effects that aren't good, then go get help. But don't just waste money and resources that you could need elsewhere just because you feel some obligation to be traumatized.
I'm sorry to mostly have to disagree. First of all, my bad for forgetting you are from country were basic healthcare like psychological councelling after trauma isn't free.
I do agree that not every traumatic event automatically leads to PTSD.
However, I would never describe being mugged at gun and knifepoint, and actually injured a 'lesser, isolated trauma'. Moreso because it happened in a place that Pisskop probably regarded as 'safe', if only because it's the familiar old route he takes every day.
Moreover, studies show that PTSD is more easily treatable, the earlier it's recognized and treatment started. That being said, EMDR treatment is not an expensive treatment. The equipment used is not that expensive, and re-usable. Nor is it an invasive or heavy treatment. It's basically just doing some eyerolling for the good doctor. The diagnosis could be the most expensive part of the treatment.
Waiting until you start to suffer symptoms in the case of PTSD could mean that several years go by, in which you develop symptoms so slowly that you won't notice it until it has become a serious problem in one of the main life factors of relation, work or physical health.
Because that's the nasty thing about PTSD. All the time, you think you're fine until it bites you in the ass.
At that point, yes, it's very likely that treatment will have become serious and possibly expensive. The costs of someone losing their job because of anxiety or irritability issues, or becoming dependent on Xanax and other legal harddrugs to combat panic attacks is much higher than an early diagnosis and treatment.
