Hi,

Yesterday afternoon I was in a minor car collision on the highway. Traffic was stop and go - I was rolling along at around 5 - 10 miles per hour, when I was suddenly rear ended by the car behind me. It felt as if she was going maybe 15 - 20 miles per hour. Her excuse was that her brakes didn't work.

My head and neck were whipped around pretty good by the impact. It was completely unexpected and my body was totally relaxed at impact. The airbag did not deploy, I suppose the collision wasn't hard enough for that. I had gone to the ER afterwards and gotten xrays of my neck - there are no visible issues.

Question is in the title. It has been around 2 years since my last concussion. It took me around a year and a half to stop experiencing daily headaches. I'm not too bad right now, the day after. Headache is mild but really not too bad.

Do I just monitor symptoms at this point if they arise? I know it's always possible in a situation like this that I've re-injured myself, but is it also possible that I got lucky and am just ok? How will I know?

Thank you.
