What Causes Sharp Pain Under Your Breasts

Experiencing sharp pain under the breasts can be a distressing and uncomfortable sensation. While it’s always important to consult a medical professional for an accurate diagnosis, there are several potential reasons behind this symptom.


Costochondritis is a common condition characterized by cartilage inflammation that connects the ribs to the breastbone. It can cause sharp, localized pain under the breasts, especially when breathing deeply or coughing. This condition is often triggered by physical strain, injury, or respiratory infections.

Muscle Strain

Intense physical activity or sudden movements that strain the chest muscles can lead to muscle strain or injury. It can result in sharp pain beneath the breasts, particularly during movement or deep breaths. Rest, gentle stretching, and avoiding activities that exacerbate the pain can help in the healing process.

Gastroesophageal Reflux Disease (GERD)

GERD occurs when stomach acid flows back into the esophagus, causing irritation and inflammation. This condition can cause a sharp, burning pain that radiates under the breasts. Managing GERD through lifestyle changes, such as avoiding trigger foods and maintaining a healthy weight, along with medications prescribed by a healthcare professional, can alleviate symptoms.

Rib Fractures

Trauma or injury to the chest area can result in fractured ribs, leading to sharp pain under the breasts. In addition to pain, other symptoms may include difficulty breathing, tenderness, and swelling. Medical attention is crucial for proper diagnosis and treatment of rib fractures.

Breast-Related Issues

Breast-related causes such as mastitis (breast infection), breast abscess, or benign breast lumps can also cause sharp pain beneath the breasts. Other symptoms like breast swelling, redness, or breast tissue changes may accompany these conditions. A healthcare provider should evaluate any breast-related concerns.
