In late 2006, I was involved in a work accident in which a 20+ pound log was dropped on my head from a tree cutting crew about 25+ feet up. I went to the hospital, had an x ray, to which the doctor said looked ok. I was discharged the same day. 2 days later, my left ear was filled with dry blood. I have had extensive back pain and chronic headaches since this incident. I recently had an MRI which was clear. Now (June 2008) my headaches are getting worse, I've been having memory loss, nausea, and tremors. I was told by a nurse that I may have post concussion syndrome. Would this still be prevelent after a year and a half? I've had no other trauma or medical condidtions since this incident. Looking for some advice.
