During pregnancy, hormonal changes and weight gain can put extra pressure on your joints, leading to pain and discomfort. Additionally, the growing uterus can compress nerves in the lower back, causing radiating pain down the legs. This condition is known as sciatica. To alleviate these symptoms, try practicing good posture, wearing supportive shoes, using heat or cold therapy, doing gentle exercises like swimming or prenatal yoga, and seeking chiropractic or physical therapy treatments. It's important to consult with your healthcare provider for an accurate diagnosis and personalized treatment plan.
