Like before, you've never had things happen, just worry about them. Whilst perhaps this could be a symptom of hypoxia, what else could it be a symptom of and how common and likely is the lesser issue? A headache or tension can be very common, and you have reasons to have those. How common is hypoxia due to altitude? Probably not driving through areas that thousands of people travel through but more a possibility for someone up a mountain in a high altitude area climbing it.
