Alamak, this happened to a few of us jugak especially kalau active sikit or jahitan tension, nurse kena monitor closely and cuci dengan betul, hopefully it closes balik soon lah. The good news is C-section wounds usually heal pretty fast even kalau terbuka sikit, tapi please follow what the nurse said exactly ye, jangan abaikan the cleaning routine because infection is a real risk. How's the pain and discharge, any pus or very red area? Kalau ada anything yang nampak off, don't wait, go back to the clinic atau hospital je sebab this really needs in-person checking.
