I broke my foot during the trip. I told the tour guide that my feet hurt, but he didn't take any measures. Can I ask him for compensation now?

If you want to claim compensation, my advice to you is that you'd better communicate with the travel agency and reach an agreement, and the travel agency will help you claim compensation from the insurance company. This is the most reasonable and acceptable way.

You point the finger at the tour guide, which has neither legal basis nor the world. Only get twice the result with half the effort. Maybe, people are angry and don't care about you at all. There is nothing you can do about it. Your injury was an accident, not man-made. You didn't go to the insurance company to make accident insurance claims, but you couldn't find a small tour guide. There are only two outcomes. First, you fight with you and wrangle. It will only delay time and have no practical use at all. Second, taking the judicial route will cost more, and you 100% will lose. Your request has no legal basis.
