Got hit in the head few days ago (Thursday night). Didn't lose consciousness, just the standard seeing stars. No dizziness, no nausea, outside of a minor headache, nothing. Felt fine for the next few todays.

Today I noticed my pupils are dilating. No other symptoms outside of a minor headache.

This isn't my first concussion. I'm also feeling quite fatigued.

What could this be? Once again, feel totally fine outside of the fatigue and dilation (and headache, obviously).

Is this normal?
