Wow,

The lack of pain and no Loss of Consciousness (LOC) mean little. The fact that you saw stars is enough to know right away you suffered a concussion. The delay in symptoms is not uncommon.

You missed one question, though.

I asked how many kids you have. You said a 3 and 7 year old. The correct answer should have been a 3, 7 and a man sized and aged child. Most boys never grow up.

My best to you.

Look at this thread. It has lots of important details on it.
Things you wish you'd known when you first got post-concussion syndrome.
