I am only adding to the wisdom of those who have tried to help before, to try and alleviate your persistent anxiety.
Often a person has an audible foot fall.......slapping, before one develops noticeable foot drop. My husband heard my slapping foot, I had not noticed..........
I am now back to normal, but fell on Sunday after tripping over a stone, this does not mean I have foot drop.......it means I am clumsy
