I have been having increased foot pain over the past 3 days. Initially, it got better on Friday night, but now it's getting worse for no reason. I have been resting a lot, pain won't stop at rest.

Varies. There are multiple reasons a person might have progressive foot pain without having necessarily have had an injury. An inflammatory condition such as gout, a neurological condition such as a radiculopathy, or a progression in arterial insufficiency are among possible causes. Don't hesitate to be checked.
