Knee Pain – What do you do?

Hey everyone, I hope this question is allowed here. I’m leaving for Japan tomorrow and curious what everyone with knee pain is taking there? Can I find something that will ease the pain?

I’m having a bit of a flare up right now and am dreading all the stairs.

Any advice is appreciated. Thank you!

Edit: Thanks for all the advice so far. I’m definitely going to be taking your recommendations.
