Costochondritis
Costochondritis is inflammation of a rib or the cartilage that connects a rib to your breastbone (sternum). It causes tenderness, and sometimes the pain may be sharp or aching, or it may feel like pressure. Pain may get worse with deep breathing, movement, or exercise. In some cases, the pain is mistaken for a heart attack. Despite this, the condition is not serious. Read on to learn more about the condition and how it can be treated.

What Causes Costochondritis?
The cause of costochondritis is not completely clear, but it may happen after a chest injury, chest infection or coughing episode. Some physical activities can sometimes lead to costochondritis. Large-breasted women may be more likely to have the condition. Often, the reason for the inflammation is unknown.

There is no test for costochrondritis. The condition is diagnosed by the symptoms you have. In some cases, tests are done to rule out more serious problems. These tests may include imaging tests such as chest X-ray or CT scan.
Treating Costochondritis
If an underlying cause is found, treatment for that will likely relieve the problem. Costochondritis often goes away on its own. the course of the condition varies from person to person. It usually lasts from weeks to months. In some cases, mild symptoms continue for months to years. To ease symptoms:

Avoid activities that put stress on the chest or spine.
Apply a heating pad (set to warm, not to high, heat) to the breastbone several times a day.
Perform stretching exercises as directed
