Mama, ito ay dapat talagang i-check ng doctor mo ASAP kasi 6 months na since CS, hindi dapat may ganitong feeling pa, pwedeng scar tissue na nag-harden or may infection na lumalaki, both need proper assessment. One of my mum friends had something similar at lumaki pa siya into a keloid, so mas better kung makita ng doctor mo agad para ma-address habang maliit pa lang, baka may simple solution na lang pero kailangan sure tayo.
