My concussion history:

- One previous diagnosed concussion, almost 20 years ago (I don't recall any significant or lasting PCS symptoms)

- Several other head impacts that I can recall, most many years ago in childhood/adolescence. I think at least one was a concussion, in that it produced a bit of wooziness and a headache that lasted for a day or two - unfortunately, this impact was pretty much at the same site as my current injury

So, in summary, I think I've had at least two prior concussions that occurred many years ago, plus a few possible impacts (also many years ago) that might have been subconcussive or even concussive. However, none of these impacts produced any major or lasting symptoms (ie, beyond a day or two).

I'm now at just over four months following my concussion this spring. I'm doing a lot better, but it's been a gradual recovery and I still have a ways to go.
