Mama, please get that checked by a doctor soon, pag biglaan tulad yan at may sakit pa, hindi dapat i-ignore kahit normal lang ang BP mo. Could be maraming things, pero kailangan ng professional na makita at maramdaman kung ano talaga. Don't worry yourself too much in the meantime, isched na ng appointment, okay? A few of my mum friends had sudden things like this din, and sure they were okay, pero nabigyan sila ng peace of mind agad pagkita ng doctor. Let me know kung okay ka na!
