I have a very close friend, who plays hockey and football. He knows of my current condition, and that I am quite obsessed with my brain health.

He constantly complains to me about getting very bad, "head pressure," when at practice and games, as well as not being able to remember the previous days events.

He had a very bad head to head hit in a hockey game about 11 months ago, which was much stronger than my concussion hit, and was experiencing concussion like symptoms, which I know that he never addressed.

Could PCS symptoms be mild enough to almost go unnoticed? I really want to talk to him about this, but I don't want make myself seem paranoid.

I know that I, who have always had chronic headache problems never realized I was concussed until about 2 weeks in. Also wouldn't the symptoms get so unbearable that it would be very hard not to notice?

Thanks in advance, Mrsmith.
