What can i do about possible surgical wound infection?

As with any: Infection, adequate drainage with removal of foreign material as much as possible, and antibiotics. Consult your surgeon for advice in your specific case.

See the doctor: Localized small infections can be rinsed with sterile saline and dressed with a topical antibiotic ointment and covered with a sterile dressing. Deeper more involved infections with extending redness past the immediate margins will likely require a more aggressive approach such as incision and drainage, debridement, and oral antibiotic. Consult with your physician as to what would be best for you.
