Could I have P.T.S.D?

This happened in 1992, and the answer really isn’t going to impact anything but I’m still wondering…
In 1992 I was seriously injured in an auto accident that left me in a coma for a month and a half. I have been curious about whether or not I could have P.T.S.D because of the seriousness despite being left in a coma right after the accident. So, what do you think? Do I have P.T.S.D, or am I just left with the impact of the crash itself?
