Eh normal ja tu sayang, especially if you're in early pregnancy or postpartum, a few of us felt the same prickling sensation, macam ada thousand tiny needles! Could be hormonal changes, ligament stretching, or just the whole area adapting, but since you're describing it as sakit-sakit and ngilu, better check with your gynae or doctor just to be sure everything's okay, can? They'll give you proper peace of mind.
