Some of the causes of pain below the right sternum that need to be considered are: gastrointestinal tract pathology, flatulence, liver and gallbladder disease, muscle soft tissue injuries, and pleurisy. The area around the right lower sternum contains the gastrointestinal tract, liver, gallbladder, ribs and costal cartilage, pleura, and lungs, and any part of the area that has a lesion can cause pain. The most common in normal people is gastrointestinal dyspepsia and intestinal flatulence, which will result in discomfort such as significant bloating and pain, which can be slowly recovered with appropriate activity. A small number of patients with pain below the right sternum may have cholecystitis or gallbladder or bile duct stones, but also liver disease such as tumors, inflammation and other conditions. Occasionally, muscle soft tissue injuries caused by knocks and pleurisy caused by chest diseases can also lead to local sensory nerve irritation and consequently painful sensations. There are numerous possible causes of pain below the right sternum, and a general surgery or thoracic surgery specialist is recommended.
