Why Does My Shoulder Hurt When I Breathe?

If your shoulder hurts while breathing, it may indicate that nerves in your upper chest or neck area are being pressed or irritated. This pressure can develop from inflammation in the chest wall, lung lining, or surrounding muscles that share nerve pathways with the shoulder. Sometimes, acid reflux or heartburn can also cause pain in your left shoulder that feels similar to a muscle strain.

At Total Orthopedics & Sports Medicine, we perform on-site imaging to quickly diagnose the underlying cause of shoulder pain and provide immediate relief through advanced treatments.

What Causes Shoulder Pain When You Breathe?

The primary causes of shoulder pain associated with breathing are pleurisy and pneumothorax. In a pneumothorax, air leaks from the lung into the cavity between the lung and the chest wall. This trapped air limits lung expansion and increases pressure, which irritates nearby nerves and causes sharp pain in the shoulder. In some cases, pleural effusion (a buildup of excess fluid around the lungs) can also trigger shoulder discomfort. Here are some other possible causes of shoulder pain:

• Muscle weakness: Weak chest muscles reduce support for your shoulder, which causes pain during breathing movements.
• Rib injury: A bruised or fractured rib increases strain on nearby muscles and leads to discomfort around the shoulder joint.
• Herniated thoracic disc: Nerve compression in the upper spine can cause pain signals to your arm and shoulder blade.
• Gallbladder inflammation: Gallstones or infection irritate the diaphragm and cause pain that travels upward to your right shoulder blade when you inhale.
• Heart issues: Angina can cause nerve irritation in the chest, which sends pain signals to the shoulder.

How Does Pleurisy Lead To Shoulder Pain?

Pleurisy can cause shoulder pain when the thin tissue (pleura) surrounding your lungs gets inflamed and rubs against the chest wall. This irritation activates the phrenic nerve, which connects the diaphragm to the shoulder. As you breathe, the movement of the inflamed pleura intensifies nerve irritation, producing sharp, stabbing pain along the shoulder blade

Additionally, the inflammation caused by pleurisy can also make it difficult for your lungs to expand fully. This restriction often leads to shortness of breath and causes discomfort while inhaling. In many cases, pleurisy develops as a result of an infection, blood clot, or autoimmune condition. Because these conditions can worsen rapidly, it is essential to contact a doctor promptly to initiate treatment.

Can Chest Wall Or Intercostal Injuries Cause Shoulder Pain While Breathing?

Yes, chest wall or intercostal injuries can cause shoulder pain while breathing. These injuries can tear or overstretch the thin muscles between your ribs, which causes inflammation and irritates nearby nerves connected to your shoulder blade. As a result, this irritation spreads pain to your shoulder and worsens when you take a deep breath or move your upper arm bone.

Due to nerve irritation, your pain often intensifies when you cough, sneeze, or twist your upper body. This type of pain originates from strained muscles and ribs, rather than internal organs. You may also feel soreness across the chest wall or under the shoulder blade. In most cases, this soreness improves with rest, light stretching, and ice pack therapy.

Can Pulmonary Embolism Cause Shoulder Pain With Inhalation?

Yes, a pulmonary embolism can cause shoulder pain when you inhale. According to a PubMed case report, a 70-year-old woman arrived at the emergency department with severe left shoulder and back pain that worsened with each breath. Doctors initially suspected a lung infection, but further testing revealed a pulmonary embolism blocking her left pulmonary artery. This blockage reduced blood flow to the lung and inflamed the pleura (a fluid-filled sac), which triggers sharp shoulder pain while breathing.

Is Shoulder Pain While Breathing A Sign Of Costochondritis?

Yes, pain in the right shoulder when breathing deeply can develop with costochondritis because the inflamed rib cartilage irritates the joints that support the chest wall. This irritation increases pressure on nearby intercostal nerves, which can send pain toward the shoulder blade and upper arm. A study published by the American Academy of Family Physicians (AAFP) found that 6% to 13% of patients with chest pain in primary care are diagnosed with costochondritis. This chest pain can extend along shared nerve pathways, potentially leading to shoulder pain.

Can Lung Cancer or Tumors Cause Shoulder Pain While Breathing?

Yes, lung cancer or tumors can cause shoulder pain while breathing. According to a study in WebMD, shoulder pain is a common symptom of Pancoast tumors, Horner’s syndrome, and mesothelioma. This pain develops when the tumor presses on nearby nerves or tissues. In advanced cases, the discomfort increases as the tumor approaches the acromioclavicular joint or spreads to surrounding bones.

Other than that, you may also notice weakness or discomfort spreading across your chest, back, arm, or hand as the tumor affects nearby nerves. Your symptoms often intensify while you’re resting and may be accompanied by difficulty breathing. However, these symptoms aren’t always caused by lung cancer. They can also result from other conditions, such as arthritis or muscle strain.

Can Cupping Therapy Help Relieve Shoulder Pain?

Yes, cupping therapy can help relieve shoulder pain by creating suction on the skin, which improves blood flow and relaxes tight muscles. This suction pulls underlying tissues upward, which may reduce inflammation and tightness in the shoulder joint. Cupping therapy also helps break down scar tissue, thereby improving shoulder mobility and reducing discomfort.

In addition, suction therapy helps stimulate lymphatic drainage, which supports the body’s natural healing response and reduces swelling around the complex joint. When you combine CT with therapeutic exercises and prescribed medications, it can speed up your recovery and reduce muscle tension. However, CT provides short-term comfort for muscle-related shoulder pain.

How Do Aquatic Therapy and Hydrotherapy Improve Shoulder Pain?

Aquatic therapy and hydrotherapy can help reduce shoulder pain by easing pressure on the joints and improving flexibility. The water’s buoyancy (low resistance) supports gentle movement, which allows you to exercise without discomfort. As the warm water increases blood flow, your muscles relax and inflammation decreases. With consistent sessions, your shoulder gradually regains strength, mobility, and a natural range of motion.

Here are the benefits of aquatic therapy:

• Pain relief
• Reduction in muscle spasm
• Retraining of balance and coordination

According to a PubMed clinical study involving 185 patients, 93 received hydrotherapy while 92 underwent land-based rehabilitation. The study found that patients treated with hydrotherapy achieved better joint mobility and faster pain relief. These results suggest that water-based therapy is more effective than traditional land exercises for improving shoulder recovery.

Why Is Regular Exercise Important in Preventing Shoulder Pain?

Playing sports regularly can prevent shoulder pain by strengthening muscles, improving flexibility, and maintaining joint stability. It enhances coordination between your shoulder and neck, which keeps your movement smooth and pain-free. However, without regular exercise, you may develop poor posture, gain weight, and experience joint swelling.

Here are some additional benefits of regular exercise in preventing shoulder pain:

• Improves blood circulation, promoting faster healing and tissue recovery.
• Prevents muscle imbalances that often lead to shoulder strain or injury.
• Boosts posture and alignment, reducing pressure on shoulder joints.
• Decreases inflammation and joint degeneration over time.
