Here We Go Again

I'm back again. 😂 Anyway.. 4 months postpartum c-section and I have questions. My incision area STILL hurts and some days it feels like a week after I had my son. Is this normal this late in the game? Question number 2: I have a specific spot on the side of my vaginal wall that HURTS when I apply pressure from either exercising, pooping, putting in/removing a tampon, etc.. It feels like something is stuck in there and it's almost like it pokes me. Help? Last thing is when I push (like trying to poop, etc.), it hurts where my incision is and feels almost as if it's "empty".. What is this? Thanks so much in advance.
