Common Causes of Sharp Pain Under Right Breast

Here are some possible health conditions that cause pain or discomfort under your right breast.

1. Stress or Anxiety

When under psychological or emotional stress, you could experience mild or sharp pain under right breast. Some people may experience it under the left breast. Stress affects the body’s digestive system, heart rate and blood pressure and causes nerves and muscles to tense up.

Having an anxiety attack could also cause discomfort around the chest area as it causes the nerves and muscles in the chest to tighten. To alleviate stress or anxiety-related pain, you can try some breathing exercises, yoga, and essential oils for relief.

2. Trapped Gas

Most people expel gas at least 10 times a day. However, trapped gas in the intestines can cause pain when you are not able to pass it. The pain may be so intense or constant that it can be mistaken for gallstones, heart disease or appendicitis. The common signs and symptoms of gas pain include:

  • Involuntary or voluntary expelling of gas
  • Cramps, sharp, jabbing pains or knotted feeling in the abdominal area
  • Bloating

Call your doctor in case of severe or persistent gas pain accompanied by bloody stools, vomiting and weight loss.

A viral infection that causes painful rashes, shingles usually appear as a stripe or stripes of blisters that wrap around the right or left side of your torso.

  • Itching
  • Sensitivity to touch

You may also experience headache, fever, sensitivity to touch, and fatigue. If you suspect that you have shingles, see your doctor immediately. The virus can pass to anyone who is not yet immune to chickenpox.

Your rib cage protects the organs in your chest. Any kind of trauma to your rib cage, such as a crush injury from an accident or a fracture from a direct blow can cause pain around the affected area. It can also lead to tenderness and bruising. The pain under right breast may feel worse when taking deep breaths, sneezing or coughing.

For such injuries, it is best to seek medical attention immediately to prevent further problems that may affect your other organs.

In some cases, a breast cancer spreads to lymph nodes around the collarbone or under the arm and result in swelling or lump. If you experience any of the symptoms, visit a professional right away for an early diagnosis and prompt treatment.

Costochondritis, also known as chest wall pain, costosternal chondrodynia or costosternal syndrome, is an inflammation of the cartilage near the rib cage and breastbone. There are different reasons why people may develop this condition. Some of the usual causes are repetitive strain to the breastbone while there are also some who develop this because they have a flu virus or they are constantly coughing. If the chest area will be strained, there is a bigger chance of acquiring this condition. You will know if you are suffering from this condition if the pain increases while you are coughing or sneezing.

The pain can range from mild to excruciating and may cause constant shooting pains that interfere with your daily routine. In most cases, this condition goes away within several weeks. Other symptoms of Costochondritis may include:

  • Pressure-like, aching or sharp pain on either side of the breastbone
  • Radiating pain to the abdomen or back
  • Pain gets worse when you move, breathe deeply or stretch

Seek immediate medical assistance if you experience severe and persistent pain.

8. Kidney Stones

The kidneys filter waste from your blood and create urine. When minerals and salts in your urine stick together, they form small or big kidney stones. There are a lot of stones that will pass through the urinary tract with ease because they are small but there are also some that may be hard to pass because they have grown too big.

They are usually unnoticed unless they cause pain and blockage. If recognized early, stones do not cause permanent damage. You will need to drink plenty of water to flush out kidney stones from your urinary system. This can be removed through surgery or by taking medications that will make the stones stuck in the kidney to become smaller.

You may experience other symptoms of kidney stones:

  • Red, pink or brown urine
  • Severe pain below the ribs
  • Pain that radiates to your groin and lower abdomen
  • Pain when urinating, foul-smelling urine
  • Urinating more often

Pleurisy is an inflammation of the pleura – a membrane lining that protects the lungs. This condition can be caused by a viral, bacterial or fungal infection, certain medication, autoimmune disorder, rib fracture, or other diseases.

The main reason why this condition is called pleurisy is because the lung and chest area is called “pleura.” Similar to Costochronditis, the pain brought about by this condition may be increased whenever there is any type of movement.
