Drain wound at 4 weeks post-op; is this normal? (Photo)

Concerned. Right drain site not healed yet. I have one tiny hole where i feel a stitch but its not poking out. It does not hurt nor does it have a foul smell to it. Is it infected, does it need debridement? Do i leave it alone? Do i cover up when i shower? I contacted PS about it and was told that im healing well and will close up, to keep it clean and not to apply antibiotic ointment just peroxide at night every day.
