Do you ever have them.
When I was a child, and also as an adult up till about 40, I'd randomly get them. It was usually while travelling, but there were other random times like sitting in a meeting.
I've just realised it was probably stress. I've always found travel and change hard.
I always used to wonder about it as no-one else had them. I wondered about seeing someone a few times, but thought it was silly and not enough of an issue.
