Aww sayang, 2 hari 2 malam tak tidur tu memang menyakitkan hati dengar, perut yang sakit memang buat orang jadi stress dan exhausted. Tapi I'd really suggest you see a doctor quickly, especially kalau dah sampai nangis-nangis tarik, sebab ada banyak reasons why perut boleh terasa macam tu (masuk angin, period cramps, constipation, atau even something that needs proper check-up), dan kena tahu exactly apa yang going on before trying anything. Once you know what it is, lotion or topical stuff boleh help with the discomfort, tapi diagnosis dulu lah yang penting, okay?
