Most people are familiar with left-sided chest pain and how it can indicate serious heart problems, such as a heart attack or other heart diseases.
Right-sided chest pain is not usually talked about as often, but can still indicate a variety of problems.
Pain in the right side of the chest can result from direct injury or inflammation of certain structures, or by referred pain. Referred pain is when pain originates in a different part of the body.
Right-sided chest pain can be caused by many different conditions, illnesses, and injuries. Here are 17 potential causes.
1. Anxiety or stress
Severe anxiety or stress can trigger an anxiety attack. In some people, an anxiety attack has many of the same symptoms of a heart attack, including chest pain, dizziness, heart palpitations, and difficulty breathing.
An anxiety attack can be caused by a stressful event or may occur randomly. As many of the symptoms are similar to a heart attack, it is crucial for anyone who is uncertain about their symptoms to seek medical attention.
2. Muscle strain
The chest wall is made up of many different muscles. It is very easy to strain or sprain these muscles by increased exercise or activity, or from stress or tension.
This type of chest pain, though it can be uncomfortable, is easily resolved with rest and pain relievers available for purchase over the counter or online.
A traumatic injury, such as from a fall, a sharp blow to the chest, or a motor vehicle accident, can damage the nerves, blood vessels, and muscles within the chest.
It is also possible to damage the heart, lungs, or other internal organs with this kind of an injury.
Anyone who has an accident like this should call the doctor or emergency services, as internal injuries are not always apparent.
Costochondritis is an inflammation of the cartilage that connects the ribs to the main breastbone in the front of the chest.
The pain from costochondritis may be severe and can be caused by intense coughing, infection, or traumatic injury.
Costochondritis usually goes away on its own, but people may need extra rest, pain relievers, and hot or cold compresses to aid recovery.
5. Rib fracture
A rib fracture is a break in the bones that protect the internal organs in the chest.
It can be very painful and can lead to serious complications if not treated correctly.
Rib fractures are usually caused by a fall or impact to the chest but can also be caused by severe coughing. If the break is on the right side, it can cause pain, swelling, and tenderness in that area.
A pneumothorax or collapsed lung occurs when air escapes from the lung and gets into the space between the lung and the chest wall.
This makes it difficult for the lung to expand when breathing and can cause sudden and significant pain or discomfort. Someone with this condition would also experience a shortness of breath, a rapid heartbeat, and dizziness. They may even collapse suddenly.
Pleurisy is an inflammation of the membranes that surround the lungs. This inflammation causes friction between these two layers of tissue, which can cause sharp and severe pain when breathing.
Usually, there is a thin fluid-filled space in between the lining of the lungs and the lining of the chest cavity. As someone breathes in and out, the lungs can glide over this tissue smoothly.
8. Pleural effusions
A pleural effusion is the buildup of fluid in between the layers of tissue outside of the lungs. It can cause chest pain and shortness of breath. Breathing may get more difficult over time, so it is essential to see a doctor.
Pneumonia is an infection of the lungs. It can be caused by many different bacterial, viral, and fungal organisms.
People with pneumonia often experience chest pain when breathing and coughing. Other symptoms of pneumonia include fever, chills, a cough, and loss of appetite.
10. Pulmonary hypertension
Over time, this makes the heart work harder to pump blood throughout the body and can cause chest pain.
11. Pulmonary embolism
Pulmonary embolism is a blood clot that has become lodged in the lungs. It can be life-threatening if not treated quickly.
If it occurs in the right lung, it can cause right-sided chest pain. Additional symptoms include shortness of breath, rapid breathing, and coughing up blood.
The pain and other symptoms of pulmonary embolism usually come on suddenly and require emergency medical attention.
12. Lung cancer
Lung cancer causes chest pain, coughing, and shortness of breath as the growth starts to interfere with the normal functioning of the lungs.
13. Chest tumors
Growths within the chest or chest wall, whether or not they are cancerous, can also cause chest pain.
As the tumor grows, it will put pressure on the nerves or blood vessels that are nearby, causing pain or discomfort.
14. Heart disease
While most people associate left-sided chest pain with a heart attack or other heart ailment, right-sided pain is also possible, especially if heart disease affects the right side of the heart.
If the affected nerves are in the chest, it can cause chest pain. Shingles tends only to affect one side of the body.
At first, shingles may cause pain and sensitivity in one area, as well as a fever. It will later develop into a painful, itchy rash.
16. Heartburn or acid reflux
Heartburn is caused by stomach acid that has passed back up into the food pipe from the stomach.
The food pipe is located within the chest, so it can cause chest pain that seems to come from the right side.
17. Liver, gallbladder, or pancreas problems
These structures play a vital role in normal digestion and have other essential functions. They are located in the top of the right side of the abdomen.
Whenever someone is experiencing chest pain, regardless of the location within the chest, they should mention it to their doctor promptly.
While there are many explanations for right-sided chest pain that are not an emergency, there are some medical conditions that require urgent care.
Signs that someone needs emergency care include:
- sudden onset of severe chest pain
- crushing pain in the chest
- chest pain with shortness of breath
- pain that radiates to the jaw or arms
- chest pain accompanied by dizziness or weakness
- change in or loss of consciousness
The outlook for someone having right-sided chest pain varies depending on the cause of the discomfort.
If pain persists despite treatment, it is important to continue to follow up with the doctor for further diagnosis and treatment.
