Granulation tissue

Anyone deal with granulation tissue postpartum? I had a second degree tear and some superficial abrasions from birth. My stitches healed well but I have one spot externally from an abrasion that’s has developed granulation tissue. It’s only painful when I have concentrated urine, even then it’s not THAT bad anymore. My OB offered silver nitrate at my 6 week visit but I wanted to see if it would heal on its own first. It hasn’t gotten much better and I’m 10 weeks pp now... so it’s been about 3-4 weeks since my appointment. Will this ever heal on its own or do i need to suck it up and do the silver nitrate?
