Mama, I know masakit yan talaga, pero para sa back pain at nausea together, please see your doctor soon, okay? Especially kung paulit-ulit na or tumatagal, kailangan tingnan ng doctor to make sure everything's okay. A few of us moms had similar symptoms before, pero lagi naming kailangan ng proper check-up para malaman kung ano talaga ang problema. Don't wait na lang, mas better na mag-consult na ngayon para may peace of mind ka. Take care, mama!
