Hello all,

Today my dog was sitting about 5 feet behind me while I was sitting at my computer and barked loudly through the screen door in order for me to let her in. This wouldn't ordinarily be a big deal, but I'm somewhat sensitive to sound. My immediate reaction was to jump and I've been a nervous wreck ever since. I feel extremely depressed now and I'm hoping I did not sustain my fourth concussion. Is there any telltale signs of a concussion? Is this just my nerves?

All help or guidance would be greatly appreciated.

Thanks so much
-Will
