c section pain

Amy • Wife ✨ Momma to a little girl & a little boy #3 on the way!
18 days PP and I've been healing great and moving around a lot.... and all of a sudden I'm in loads of pain at my incision.... I've had my mom look and she said it doesn't look infected, actually looks good. Even saw my OB earlier in the week and she said I looked great. But yesterday the pain got bad... and last night and this morning I'm almost in tears and it hurts to walk. I feel like my whole area down there is sore to the touch.... it feels like the incision itself hurts but when I touch it's more in my pubic area. I have no clue. Probably scheduling an appointment for the morning. But anyone have any similar issues?
