Aiyooo, I feel you lah! A few of us mums dalam circle still kena back pain after more than a year, and honestly it's really the carrying, bending, and picking up kids that trigger it most. One of my mum friends went to see a physiotherapist and she said it helped her a lot, so maybe worth checking with your doctor first to rule out anything serious, then can try physio or some gentle stretching at home? Paracetamol and a heat pad juga membantu during flare-ups, and I try to be more careful with my posture sekarang (easier said than done when you're chasing toddlers haha). Hope you feel better soon!
