Mild evening foot swelling is very common and normal at 22 weeks of pregnancy. Medications, including water pills, are generally not safe or recommended. Instead, you can safely manage this with these simple steps: 1. Elevate your feet above heart level when resting. 2. Avoid standing or sitting for long periods. 3. Drink plenty of water. 4. Wear comfortable shoes or light compression socks. While this is normal, please contact your doctor if you experience sudden swelling in your face or hands, severe headaches, or vision changes, as these require medical evaluation.
