Its all very interesting... thanks for the replies!

PTSD was just never something that occurred to me. I assumed I need to have flashbacks or something. I mean, when I've had previous falls from horses I've been able to play them over and over in my head, relive the sensations, the whole shebang... but not this time.

The only "memory" I have at all is the noise my helmet made when it cracked in 6 places when it hit the ground. I remember thinking " Was that my skull?" (which it wasn't) and that's it.

So I guess the real question is where to go from here?

The easily startled thing isn't my worst symptom but it does cause me problems. But I have no idea of how to resolve it. I've asked my family to do their best to not do surprising things, but that only goes so far.
