Alamak, memang la gatal jahitan bersalin tu adalah part of healing, luka yang dok menyembuh selalu gatal macam tu, tapi I understand la, nak tidur pun terasa! Since you've had the wound checked twice already and they said infection-wise okay ja, the itch biasanya just means healing is happening, tapi kena make sure you're not scratching (I know, easier said than done lah ). A few of us yang dok gatal macam ni swear by keeping the area clean and dry, maybe tepuk-tepuk lembut je pakai kain bersih instead of scratching, and some mums just tolerate the itch knowing it'll pass; tapi honestly, since the stitches are loose and you're still seeing threads, I'd ask your doctor during your final pantang check-up to make sure everything is healing properly even with the loose stitches, some of them tighten on their own as tissue closes, but best to get it confirmed, can give your mind peace jugak!
