Aw, back pain during pregnancy or postpartum is really tough, a few of us mums have been there! The best thing talaga is to check with your OB or doctor kasi they can pinpoint what's causing it and give you safe relief options, especially if you're pregnant or breastfeeding pa. In the meantime, proper posture, warm compresses, and maybe some prenatal yoga or stretching can help (one of my mum friends swears by this), but definitely don't wait if it's getting worse, better safe than sorry!
