What could cause pain between my breasts? It hurts when I breathe, move my shoulders up, or even to touch it. It is almost unbearable.
Pain between breasts is due to the underlying breast bone. It is also called sternal pain. The breast bone is the flat strong bone in the middle of the chest.
Function of Sternum
Breast bone is an important bone due to its location; it protects the vital organs of the body, such as the heart, the lungs, the esophagus and the air ways.
Second important function is that it connects one end of the ribs, and the shoulder bone i.e. Clavicle forming a Ribcage.
Causes of Breast Bone Pain
- Hyperacidity or esophageal reflux can cause burning pain under the breast bone. Some times this sharp pains are mistaken for cardiac pain.
- Pain in the joints of the sternal bone and the ribs, and the shoulder bone. This is due to the stress while lifting weight, it is also called Costochondritis. The pain is more felt when the shoulders are stretched, or when a person bends.
- Intercostal Myalgia, it is the pain due to the pectoral muscles and the intercostals muscles, the muscle attached to the ribs. These muscles are attached to the sternum, when there is strain to these muscles or if they are stretched like in case of asthma, chronic cough, and other respiratory disorders.
- Sternum is a strong bone, there is very rare chance of fracture, but some times in accidents like car accidents the sternum can get damaged and give rise to pain. In cardiac surgery the bone is manipulated giving rise to long term pain in some individuals.
- Cardiac condition like coronary artery disease, angina, and myocardial infarction can give rise to Substernal pain.
- Respiratory condition like chronic bronchitis, COPD, can be the cause for sternal pain.
- At times psychogenic pain can also occur where there is palpitation, and burning in the epigastric region.
- Other cause can be hiatus hernia, excessive belching.
In your case the pain looks to be due to intercostal myalgia, or costochondritis, but if the pain persists or if it is excruciating, a physician advised is necessary to rule out any other serious condition.
