Is it possible for symptoms to be delayed up to 6 weeks (or more) following the initial injury? I remember feeling fine after the accident but after 6 weeks i feel like things really started to kick in...

I remember thinking "oh, this concussion thing isnt so bad"...but i was wrong

It is not uncommon for concussion symptoms to be delayed, especially if the concussed person lives a high stress lifestyle or tends to like to party. The brain finally reaches a point of exhaustion and the symptoms can start to build.

Yes, absolutely. It took me about three weeks after my concussion to fall into the pits of PCS. In fact, I remember thinking how crazy it was that everyone made such a big deal over my fall when I didn't even wake up with a headache the next day. Boy was I wrong! Ha.

Oh yeah, 5 months in and 2 minor set backs so far. Learning the hard way.

Ditto, oh yes it can, please take extra special care of yourself.

Yes, I'm in the same boat here. My symptoms started around a month after the initial blow to my head. After the MRI etc my doctor had said that it was possible that I had a mind concussion but that I seemed ok(!). I wish I had known to rest! I continued with everything, work, partying, travelling and then BAM! full-on symptoms a month later. I'm now looking after myself (have had 2 weeks off sick leave, now working again which is exhausting) but worried about how long it will last.

I wish you the best in your recovery!

Yes, it's very possible. I left the hospital with a headache, felt fine for a few days... actually went to work! Then BAM.... it hit me and just got worse.
