Left Chest Pain During Deep Breathing: Possible Causes - Pulmonology

Share to:

During deep breathing, there is a slight pain approximately 8 centimeters below the left nipple?


The onset of the symptoms occurred during a side-sleeping position, and I was unsure if it was due to a hiccup.
Upon waking up, I felt some pain.
Currently, it is the fourth day, and any deep breath causes pain, which intensifies with greater force.
The pain is located approximately at the junction of the left chest and abdomen.
The level of pain is bearable, but it is somewhat uncomfortable.
I would like to ask the doctor what symptoms this might indicate.
I understand that an online text consultation cannot provide complete accuracy, but I just want some reassurance before I have the opportunity to see a doctor.
Thank you.

More Info


Left chest pain during deep breathing can be concerning, and it's understandable that you're seeking reassurance before visiting a doctor. Based on your description, there are several potential causes for your symptoms, which can range from benign to more serious conditions.

1. Musculoskeletal Issues: One of the most common causes of left chest pain, especially when it worsens with deep breathing, is musculoskeletal pain. This can occur due to muscle strain, inflammation, or irritation of the muscles and ligaments in the chest wall. If you were sleeping on your side, it’s possible that you may have strained a muscle or irritated the rib cage. This type of pain is often sharp and can be exacerbated by certain movements or deep breaths.

2. Costochondritis: This is an inflammation of the cartilage that connects a rib to the sternum. It can cause localized pain that worsens with deep breathing, coughing, or certain movements. Costochondritis is generally benign and often resolves on its own, but it can be uncomfortable.

3. Nerve Irritation: Sometimes, nerve irritation or compression in the thoracic spine can lead to pain that radiates to the chest area. This can happen due to poor posture, sleeping positions, or even stress. The pain may feel sharp and can be triggered by deep breathing or certain movements.

4. Pulmonary Issues: While less common, it’s important to consider potential pulmonary causes. Conditions like pleuritis (inflammation of the lining of the lungs) or a pulmonary embolism can cause chest pain that worsens with deep breathing. However, these conditions are usually accompanied by other symptoms such as shortness of breath, coughing, or fever.

5. Cardiac Concerns: Although your symptoms seem to suggest a musculoskeletal issue, it’s crucial to rule out any cardiac problems, especially if you experience any additional symptoms like radiating pain, sweating, nausea, or shortness of breath. Heart-related pain can sometimes present as discomfort in the chest that may worsen with deep breathing.

Given that your pain started after a specific incident (side sleeping) and has persisted for several days, it leans more towards a musculoskeletal issue. However, if the pain worsens, changes in nature, or if you develop new symptoms, it would be wise to seek medical attention promptly.

In the meantime, consider the following self-care measures:
- Rest: Avoid activities that exacerbate the pain.

- Ice or Heat: Applying ice packs or heat pads to the affected area may help alleviate discomfort.

- Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce pain and inflammation.

Ultimately, while online consultations can provide some insights, they cannot replace a thorough physical examination and diagnostic testing when necessary. If your symptoms persist or worsen, please consult a healthcare professional for a comprehensive evaluation. It’s always better to err on the side of caution when it comes to chest pain.
