Ay, sakit ng puso at likod/balakang together ay common talaga especially pag stressed or overworked kami, but since parehong areas ang nakakasakit, mas okay siguro i-check mo na ng doctor para sigurado, baka posture issue lang or something more, hindi natin alam agad. A few of my mum friends din nag-experience nito pag sobrang tired or pag matagal standing/sitting, kaya get it checked lang para peace of mind mo!
