I almost can't believe this happened again. Anyway for you who don't know I got a concussion March 5th. After sitting out for a while I got released to play my sport again about 3 weeks ago. Last week I got knocked out and received another concussion. I was down for about 30 seconds. Been dealing with headaches,nausea, dizziness, tiredness, light sensitivity, and jacked up memory. I have notice a worsening of symptoms and have started to experience a feeling of pressure in my head. Has anybody had an increased intracranial pressure a week after a concussion? Maybe I just need to rest more.
