Present state

I had a concussion mid november. Am a fair bit better now and seem to be progressively improving. Main remaining symptoms are:

* certain multitasking is very hard. Eg reading phone while talking to someone
* motion, such as turning or braking in a car, especially if I'm caught unawares

This motion is easier in a train or bus as it's less sudden and I can also stand to brace against shocks.

Other than that, no big issues. Can read, work, exercise, etc. Sometimes have a mild headache if I haven't had enough sleep, which I didn't have previously, though this is decreasing. Had a cold recently and seemed worse in sinuses, though I did have ones this bad as a kid.

But before I get to flights, I did have one big car related setback a month ago. A friend braked and I wasn't expect it. I went forwards in my seat. Hit nothing, but the forward motion caused renewed symptoms. I'd say it set me back 3-4 weeks. I decided to avoid cars after that: my doctor said they could be an issue for up to six months, based on what I said. Fortunately I live in a pedestrian city so this hasn't been an issue.

Flying?

So, I had a trip planned in a month. I haven't flown since the concussion. Given my current symptoms, is it possible/plausible that flying will cause a sudden regression the way the car incident did?

I already talked to my doctor about this of course, and she said she couldn't be sure. So I'm interested in hearing the experiences of others. Did you fly and have no issue or only minor issues? Or did you fly and have a sudden worsening if symptoms that persisted?

I'm wondering if I should avoid planes for a few months too in order to be on the safe side. I had felt great before the car thing, mostly recovered.
