Uy, totally normal yan sa 23 weeks, maraming sa amin nag-complain ng same thing, especially pag lumaki na ng tyan at nagbabago ng posture! Iniwan ko lang na standing too long yung culprit, so nag-invest ako ng good pillow for sleeping on my side at nag-stretch every morning, at talagang tumutulong. Pero alam mo naman, if it's really painful or nag-radiate pa sa legs, better mention it sa OB mo next check-up para ma-rule out kung may ibang concern, sayang kung worried ka lang the whole time, diba?
