I used EXTREMELY expired Neosporin, should I be worried?

I got a minor infection on my toe from an ingrown toe nail and used Neosporin to heal the infection, I used it 3 times today, it seemed to help, but I didn't notice that the Neosporin was from 1996... Should I be worried and go see a doctor, or should I wait to see if it gets better? I also washed it off... show more I got a minor infection on my toe from an ingrown toe nail and used Neosporin to heal the infection, I used it 3 times today, it seemed to help, but I didn't notice that the Neosporin was from 1996...

I also washed it off right after I noticed it was expired and used a different antibiotic.
