Ay mama, ganyan talaga sa third trimester, ang buhay! A few of us went through that sharp back pain, especially on one side, at ang iba naman sabi nila it's the baby's position plus the ligaments stretching na sobrang painful talaga, kaya siguro best to mention it sa OB mo sa next visit para ma-check if it's just pregnancy-related or kung may adjustment needed ka. In the meantime, maraming mums swear by prenatal massages or even just warm compress, at ang pag-sit and stand slowly, hindi biglaan, talaga namang tumutulong, pero alam mo kung gaano kasakit kaya don't push it if kailangan mo talaga ng support!
