My foot is being very difficult. It's complicated.?

It sounds more like it's either tight muscles or tendons, it's hard to know for sure at this time. Either of them will free up in time to make life easier but it will be painful until then. It's possible for one trained in the muscles and tendons to get you out of pain now but finding that person will be hard. The medical people don't get into the freeing up of muscles and don't work on the tendons at all. In less than 10 minutes the right person would have you out of pain.
