Sure. Take pain - it is measured on a scale of 0 to 10. Last time I was overseas, I had a migraine attack with pain at 8 the day before the flight. Then the pain subsided, and on my 11 hr long flight to JFK, I had pain at 2. I was so happy! I would often picture my misery had I still had pain at 8 while strapped in a seat for hours. In comparison to that, mild pain was nothing. Maybe you go further in that you don't even recognize mild symptoms.
