"When am I out of the woods as far as concussions go?"

I don't understand what you mean by this question. Are you anticipating concussion symptoms or pre-occupied with worry that concussion symptoms will manifest ?

Both! Maybe I'm just still in shock as to how I wasn't hurt worse! I know it'll do me no good to sit here and be anxious.

Update: tonight I felt somewhat out of it and later vomited. Nausea persists... It came on when I went outside to take a walk after dinner - I had walked the dogs several times today before that and even went and got lunch at a busy bakery. I did feel ill immediately after dinner but drank some ginger tea and it went away.

Fearing the worst... maybe it's just anxiety. I may tell my employer that I'm not ready to return next week.

My symptoms showed really slowly... nausea, unbalanced, distracted easy, insomnia then low grade seizures after a month.

I worked as a computer architect so I know NOW I was picking a scab with the analysis that week
