question: I had a second c section 7 months ago. Everything was fine, healed great. About a week ago, I started having some mild pain where the two scars met on my right side. It started swelling more each day & becoming more painful. Then, 2 days ago, the \"knot\" under the skin was about the size of a small grape. I pulled up on my stomach to see it better & the cyst exploded. Pus & blood literally shot onto my bathroom wall. Nasty. So I continued to push on the area around the hole & a ton of pus came out. It feels better now, but am unsure if I need to get it looked at by a doctor. Could the scar be infected this long after surgery?
