What Causes Sharp Pain Under Right Breast During Pregnancy?

Experiencing sharp pain under your right breast during pregnancy can be concerning, but it is a common issue that many expectant mothers face as their bodies undergo significant changes to accommodate the growing baby. Understanding the causes of this pain can help alleviate any anxiety you may have about it. Here are some potential reasons for the sharp pain:

1. Cartilage Expansion

During pregnancy, the cartilage attached to your ribs can loosen and expand due to hormonal changes. This expansion can lead to inflammation and discomfort under the right breast area.

2. Increased Uterine Pressure

As your uterus continues to expand to accommodate the growing baby, it puts pressure on your rib cage and surrounding areas, including your right breast. The increased pressure can result in sharp pain or aches in that specific region.

3. Breast Size Changes

As your body prepares for breastfeeding, your breasts tend to increase in size and weight during pregnancy. The added weight and changes in breast tissue distribution can contribute to discomfort and sharp pain under the right breast.

4. Poor Posture

During pregnancy, changes in your body’s center of gravity and the added weight from the growing baby can impact your posture. Poor posture, such as slouching or hunching over, can strain the muscles around the right breast area, leading to sharp pain.

5. Round Ligament Pain

Round ligament pain is a common occurrence during pregnancy, particularly in the second trimester. This sharp, stabbing pain can occur on either side of the abdomen, including under the right breast, as the round ligaments stretch to support the growing uterus.

6. Muscle Strain

Carrying the extra weight of pregnancy can strain the muscles in your chest, back, and abdomen. Any sudden movements or overexertion of these muscles can result in sharp pain under the right breast due to muscle strain.

7. Digestive Issues

During pregnancy, hormonal changes can slow down digestion and lead to issues such as bloating, gas, or heartburn. These digestive problems can cause discomfort and sharp pain that may radiate to the area under the right breast.

8. Braxton Hicks Contractions

Braxton Hicks contractions, also known as practice contractions, can cause tightening and discomfort in the abdomen and lower chest area. These contractions, which are typically harmless and help prepare your body for labor, may contribute to sharp pain under the right breast.

9. Underwire Bra Discomfort

Wearing underwire bras during pregnancy, especially ones that may be ill-fitting or too tight, can exert pressure on the breast tissue and rib cage. This pressure can lead to sharp pain under the right breast, highlighting the importance of wearing comfortable and supportive maternity bras.

10. Stress and Tension

Stress and tension can manifest physically in the body, leading to tightness and discomfort in the chest and breast area. Emotional stress during pregnancy can exacerbate any existing muscle tension or strain, resulting in sharp pain under the right breast.

11. Costochondritis

Costochondritis is a condition that causes inflammation in the cartilage that connects the ribs to the breastbone. Pregnancy-related hormonal changes and increased pressure on the chest wall can trigger costochondritis, leading to sharp, localized pain under the right breast.

12. Gallbladder Issues

In some cases, sharp pain under the right breast during pregnancy may be linked to gallbladder problems, such as gallstones or inflammation. If the pain is persistent, severe, or accompanied by other symptoms like nausea or vomiting, it is essential to seek medical attention to rule out any underlying gallbladder issues.
