Right rib cage pain when lying down

Most people are conscious that if you feel pain on the left side of your chest, it might have something to do with your heart. However, what should you do if you experience sudden, sharp pain under your rib cage on the right side of your body?

In this post, we’ll discuss some of the reasons you can experience pain under your right rib cage. Along with this, we’ll tell you about when you should seek medical treatment.

Sudden Sharp Pain Under Right Rib Cage

Just under the right side of your rib cage lie several important organs, such as the pancreas, gallbladder, right kidney, and parts of your liver, and small and large intestines. Experts divide the abdomen into four quadrants, and the upper quarter on the right-hand side is the RUQ or right upper quadrant.

Sudden, sharp pain in the RUQ is not usually a cause for concern – some individuals may suffer from gas accumulating in the large intestine where it bends under the rib cage, called a hepatic flexure. This is especially true if you suffer from bowel disorders or gastrointestinal discomfort regularly.

Another reason for pain under the right rib cage is if you’ve strained or injured your intercostal muscles. These muscles line the rib cage and facilitate its movement. So, for example, if you’ve twisted or turned your body or sat at your desk for too long before getting up, you could have pulled one of these muscles. Allowing the body to rest should alleviate symptoms.

When Should I Go To The Hospital?

Crucially, sudden sharp pain in the RUQ can be a sign that something is wrong. Most commonly, especially if the pain is excruciating, happens after you eat a large meal or lasts a long time, you may have developed gallstones. These are formed when there is too much cholesterol in your bile, a substance the gallbladder stores to aid digestion.

Liver problems can also lead to pain under the right rib cage. This can be due to hepatitis, the development of an abscess, or more rarely, a cancerous growth. Symptoms include fatigue, nausea, tenderness in the area, fever, and dark urine.

The kidney is also susceptible to infection, cancer, or the development of kidney stones. Symptoms of kidney issues may involve fever, fatigue, and nausea. But if your urine is bloody or smells bad, it is a serious sign, as is painful or frequent urination.

If your symptoms coincide with any of the above, you should see a doctor as soon as you can.

Costochondritis is inflammation where your ribs join the bone in the middle of your chest (breastbone). It can cause sharp chest pain, especially when moving or breathing. It usually gets better on its own over time.

Check if you have costochondritis

Costochondritis may cause sharp pain in the front or side of your chest.

The pain may be worse when:

  • moving your upper body
  • lying down
  • breathing deeply
  • you press the middle of your chest

Urgent advice: Get help from NHS 111 if:

  • you think you have costochondritis

It is important to get chest pain checked to rule out other more serious conditions.

You can call 111 or get help from 111 online.

Immediate action required: Call 999 if:

You have sudden chest pain that:

  • spreads to your arms, back, neck, or jaw
  • makes your chest feel tight or heavy
  • started with a shortness of breath, sweating, feeling sick or being sick
  • lasts more than 15 minutes

You could be having a heart attack. Call 999 immediately as you need immediate treatment in hospital.

Treatments for costochondritis

Costochondritis usually gets better on its own, over time. It can last for a few weeks to several months.

Painkillers that help with inflammation, like ibuprofen, may be recommended to help with the pain.

If you have very bad pain that does not get better over time, you may be offered a steroid injection to help reduce inflammation or local anaesthetic to ease the pain.

Causes of costochondritis

It is not always known what causes costochondritis, but it may be caused by:

  • an injury to your chest
  • repetitive upper body movements, like lifting
  • coughing a lot

Sometimes it may be caused by a problem with the joints in the back, or another underlying condition like fibromyalgia or rheumatoid arthritis.

It can also be caused by an infection.

Why does my ribcage hurt when I lie down?

Sleeping on your side can put excessive strain and pressure on your ribcage, arm, and shoulder and thus may be the cause of your aches and pains in the morning. If you have a traditional flat mattress, this may exacerbate your pain even more.

When should I worry about right rib pain?

Contact your doctor immediately if you experience severe pain when breathing in or moving your body into a specific position, or if you have any difficulty breathing. If you feel pressure or have pain in your chest along with rib cage discomfort, call 911.

Why does it hurt under my right rib when I lay down?

Pain below your ribs can be caused by your GI tract, like GERD, indigestion, gallbladder disease, or constipation, or problems with your lungs, like pneumonia. You may also have nausea, bloating, chest pain, coughing, or pain that's worse when you breathe in.

What organ lies behind the right rib cage?

The liver is located under the ribs on the right hand side of the body. It lies just below the lungs, under the top of the diaphragm to which it is attached. The diaphragm is the muscle beneath the lungs which regulates our breathing.
