I had a C-section before a month. A few days after, it was found that the surgery site got infected with some discharge. All the stitches were removed and the site was irrigated and cleaned everyday for over a week with antibiotics. Two days ago, I went for secondary closure. A nylon thread was used and since then, the stitches dripping out some substance like a mixture of blood and a colorless fluid. We are cleaning the site with medical spirit till now. What is the reason for this dripping? Is it normal? Is that a sign of healing?
