Uy, that's unusual talaga! Itching on palms and soles can sometimes be hormonal changes, especially if pregnant ka, or it could be something like dermatitis or even just dry skin from the weather, pero honestly, mas safe na i-check mo with your doctor para sure, lalo na kung first time mo lang talaga mag-experience nito. One of my mum friends had something similar during pregnancy and it turned out to be cholestasis, so better safe than sorry na lang! Let me know what the doc says ha, hoping it's nothing serious.
