Bumps on belly above c-section scar

Okay so basically I have these bumps above my c-section scar area and I’ve had them before but that was right after my c-section while it was healing and I was told it was just due to the nerves trying to heal but that was almost two years ago and I’m currently 38 weeks pregnant now about to have another c-section in a week and these bumps have appeared again and I’m worried maybe I have an infection but idk how since i haven’t been cut open yet!! I read online, which is always an awful thing to do, that it could be cellulitis 😕 this literally just appeared earlier today and I have an appt tomorrow with my OB to ask her about it but was hoping to see if any ladies here have dealt with this? Or have any ideas what it could be? I still have no feeling in this area of my stomach either so idk if it’s something to do with my nerves again but I seriously doubt it since it’s been nearly two years since my last surgery in that area....I’m really nervous and scared right now especially since I’m supposed to be under going another c-section in one week 😢😭 please give me some words of encouragement or something

TIA 💕

*it is not stretch marks with loose skin, it does not stay around like I said it only came around right after my surgery and then disappeared after healing and has now reappeared, it is swollen
