"Causes of Pain in Right Side of Chest
The causes of pain in the right side of the chest are diverse, ranging from the effects of excess physical activity to infections and underlying medical conditions.
Here will list some of the best explained causes.
Viral Infection: Infection by the viruses that are responsible for the cold or flu has also been linked to pain on the right of the chest side. The chest pain may become more pronounced with deep breathing and coughing.
Gastritis: Gastritis, or inflammation of the stomach lining, usually occurs after fasting or excessive alcohol consumptions and it can cause abdominal pain and pain in the right side of the chest.
Pleural Inflammation: Inflammation of the pleural tissues that surround the lungs can cause pain in the right side of the chest, and in some cases the pain gets worse with deep breathing and coughing.
Gallbladder Diseases: Gallbladder attacks often manifest as pain in the right side of the chest due to inflammation of the gallbladder, and this may become most noticeable after eating foods that are rich in fat. You may also experience pain if gallstones become lodged in the bile duct.
Digestive Tract Disorders: Digestive tract disorders that involve the esophagus often lead to tightening of the chest, which can manifest as pain in right side of chest.
Liver Inflammation and Hepatitis: Inflammation of the liver can cause ‘popping' in the chest, as well as pain in the right shoulder or pain in the right side of the rib cage and back. Similarly, right side chest pain may be due to hepatitis, which is a disease that causes swelling and inflammation of the liver. Your physicians will need to conduct medical tests in order to diagnose hepatitis.
Injury: Recent injuries, such as a minor rib displacement or a neck problem, may be the underlying causes for right side chest pain.
Pancreatic Dysfunction: Inflammation of the pancreas can lead to abdominal swelling that may radiate pain into the chest.
Gastroesophageal Reflux Disease (GERD): GERD is a chronic condition in which the contents of the stomach flows back up the esophagus. Irritation to the esophagus can manifest as chest pain.
Thoracic Tumors: Tumors that develop within the lungs or in the surrounding areas can lead to pain on the right side of the chest.
Side Effect of Antacid: Chronic antacid use has been linked to pain in the right side of the chest.
Overexertion: Strenuous activities that require use of the chest muscles may lead to pain in the right side of the chest. The pain is probably related to muscle soreness and it may be worsened by particular movements.
Stress: Stress can exacerbate digestive system disorders, which lead to pain on the right side of the chest. Some key stressors are work, school or family and relationship problems.
Muscle Pulls: Pulls of the muscles or ligaments in the chest and injuries to the ribcage may lead to right side chest pain.
Food Blockage: Blockage of the esophagus with food or beverages causes congestion, which can lead to pain in the right side of your chest."
