Round ligament pain is commonly felt during the second trimester of your pregnancy and is not dangerous. You will usually feel it as a sudden, sharp stabbing sensation that often occurs when you suddenly change positions. It usually starts deep in your groin area and then radiates up and outwards towards the top of your hips. Sometimes you will experience the pain as a long-lasting dull ache deep in your pelvis or inner thighs after a full day of activity.
Your round ligaments secure the uterus to your pelvic wall. You have one on each side of your uterus. As your uterus moves in response to your movements, these ligaments will be stretched. As the uterus gets bigger, the tugging will get stronger, sometimes causing pain. In your third trimester, the uterus reaches a size large enough to prevent it from moving much. The ligament pain will therefore decrease in frequency and intensity.
If you are having severe ligament pain, lie down and rest with a pillow between your knees. Bringing your knees up towards your abdomen can also alleviate the discomfort. You can also try the Cat/Cow yoga pose or take a warm bath, which is safe at this stage of your pregnancy.
If you get these pains frequently, talk to your health care provider about getting a maternity belly support belt to minimize the movement of your uterus.
If the pain is very severe, contact your health care provider immediately to make sure you are not having any other serious issue with your pregnancy or body. If the pains are frequent, you should contact your health care provider immediately since they could be signs of early labor.
