We would need to see you in person for an accurate diagnosis, but a foot dragging along the floor usually means a condition known as foot drop. Foot drop is actually more of a symptom, one which can develop in response to several underlying anatomical, muscular, or neurological conditions.

In many cases, the root cause of the dragging foot is a nerve injury, particularly with the peroneal nerve, which is responsible for controlling the muscles used to lift the foot. This nerve can become damaged in response to trauma, injury, and other circumstances which constrict it.
