What should I do about knee pain after driving?

I visited Yeosu last week.

This is the first time my knees have hurt during a long drive.

I've never experienced this before, but even with auto mode, I think I pressed the brake pedal quite a bit when stopping and going.

My knee was aching and I was limping while walking.

Should I see an orthopedist? What's the best way to do hot or cold compresses?

This is the first time something like this has happened, so I'm quite flustered. ^^
