Hernia wound infected

I had an operation recently for an Inguinal hernia. You can
see on the right the scar.
The scar is between five and six inches long and you can see that there is an opening along the scar. The pale colour in the opening is an infection and it hurts like hell. The area around the scar is numb to the touch. It is an odd sensation to have no sense of feeling when I touch the area with my finger but for it to actually hurt when I move.Not sure if this is because the wound is quite deep or some other reason.

I have been taking Ciprofloxacin to get rid of the infection. It is working because the wound above is a lot better than it was. I am a bit worried that even though I have been on the antibiotics for about a week now the wound has not closed yet.
