Its great that your symptoms aren't to serious however most of us started with a tingling toe! P/N is sneaky, I have found out for me that it sends a warning of the next phase by making that area numb or tingly before it goes into remission only to come back later in the same area with full force.

Good your getting in early though and hopefully it was just a one off thing. What is the name of your antibiotic?
some are big creators of P/N
