There was a French knight who literally wrote the book on Chivalry, IIRC, who had medieval PTSD. I think it was Agincourt he took part in and found himself flinching any time he saw a bird fly in the edge of his vision. The difference between medieval knights and the modern soldier though, is that knights were born and bred for their position as warriors. The closest equivalent to the modern soldier would be the Vietnam draftee and a medieval levy. One of the ways soldiers often avoid psychological disorders or great grief is by talking to their comrades. Medieval soldiers had much more time to do this, and it's been theorized that's how they avoided PTSD. The earliest mention of anything that could be interpreted as PTSD is from a 19th Century text that mentions soldiers' "war fatigue."

I've read something about that - like how the baggage train and the march to and from battle was a way to get rid of the stress, by conditioning yourself that you were going to fight or that it was over, and that nowadays the more abrupt change from battle to civilian life makes it harder. 

I do, however, remember accounts of knights being unable to sleep, gritting their teeth and crying whenever the sound of metal clanging was heard. So PTSD was probably a thing back then too - I just don't think people could admit it, since there was practically no psychology and it would be seen as pussying out. Hell, it was, and it could be punished by execution during WWI.
