It is not uncommon for women to experience chronic pelvic pain during their second pregnancy, even if they did not have it with their first child. There are several possible causes for this pain, including increased pressure on the pelvic area, changes in hormone levels, and stretching of ligaments and muscles. To find relief from the pain, you can try various methods such as practicing good posture, using a support belt or pillow, doing gentle exercises or stretches recommended by your healthcare provider, taking warm baths or using heat packs on the affected area. If the pain persists or becomes severe, it is important to consult with your healthcare provider for further evaluation and guidance.
