Cold sore

Hey guys so growing up I used to get cold sores about twice a year and they usually came when I was in strong or cold winds. I also got them two separate times at Jillian (could be from wind/cold, or maybe elevation?, not sure)

However I haven’t gotten them in 2 1/2 years, honestly maybe it’s from wearing my mask and the wind doesn’t hit my lips, not sure the reason, or hopefully I grew out of it.

Anyways, I’m going on a plane for the very first time this summer, I’m really scared if I’ll end up getting one due to the high elevation of a plane. Those of you who experience cold sores, have you ever gotten it after a plane? Would it help putting cold sore medicine on my lip right before I go on the plane even if I have no symptoms of it coming?

Please let me know guys.

Thank you
