Sana my sumagot.

Ay mama, nakaka-alala yan lalo na pregnant ka pa, the combination ng back pain from your first pregnancy plus this new left butt cheek pain sounds like it could be pinched nerve or sciatica, especially since it shoots down your leg when you move. A few of us moms experienced similar pain during pregnancy, and honestly ang best reassurance we got was from our OB kasi pregnancy changes so much sa posture at pelvic alignment natin, so kailangan talaga para-check up with your doctor agad para malaman kung ano exactly ang nangyayari at safe na exercises or stretches para sa iyo. In the meantime, try pacing yourself with movement, stay off hard chairs, at maybe a pregnancy pillow helps with sleeping positioning, pero please don't delay the doctor visit ha, especially with the shooting pain. You've got this, mama!
