Ay sis, swelling ng paa ay normal sa pregnancy especially ngayon na 22 weeks ka na, pero importante talaga na i-check mo ito sa OB mo para sigurado lang na walang other concerns! A few of us tried elevation, literally pataas ng paa habang tulog or nag-relax, plus reducing salt intake at drinking tons of water, and it helped, pero iba-iba talaga sa bawat mommy kaya better safe than sorry with your doctor. Wishing you feel better soon!
