Shoulder Pain: Causes, Evaluation, and Treatment Options

Shoulder pain can come from the joint, tendons, muscles, ligaments, or nearby nerves. Common causes include rotator cuff irritation or tears, bursitis, arthritis, frozen shoulder, instability, and injuries. The right treatment depends on the cause, symptom severity, medical history, and how the problem affects daily activity.

What commonly causes shoulder pain?

The shoulder has a wide range of motion, which also makes it vulnerable to overuse and injury. Pain may develop gradually or begin after a fall, lifting injury, repetitive overhead work, or sports activity.

Rotator cuff problems: Tendon irritation, impingement, or a partial or complete tear can cause pain with lifting or reaching.
Bursitis: Inflammation of the cushioning sac around the joint may cause tenderness and painful motion.
Arthritis: Cartilage changes can lead to stiffness, aching, and reduced range of motion.
Frozen shoulder: Pain and progressive stiffness may significantly limit movement.
Instability or dislocation: The upper arm bone may partially or completely move out of the socket.
Referred pain: Neck or nerve problems can sometimes be felt in the shoulder or arm.

When should shoulder pain be evaluated promptly?

Seek urgent medical attention after a major injury, when the shoulder looks deformed, when you cannot move the arm, or when pain is accompanied by severe swelling, sudden weakness, numbness, chest pain, shortness of breath, sweating, or nausea. Schedule an evaluation when pain persists, repeatedly interrupts sleep, causes weakness, or limits work and daily activities.

How clinicians evaluate shoulder pain

An evaluation usually starts with questions about when symptoms began, the location and pattern of pain, previous injuries, and activities that make symptoms better or worse. A physical examination may assess strength, range of motion, tenderness, stability, and neck or nerve findings. Depending on the suspected cause, imaging may include X-rays, ultrasound, or MRI.

Established treatment options

Many shoulder conditions improve with nonsurgical care. A clinician may recommend temporary activity changes, ice or heat, appropriate pain medication, and physical therapy focused on mobility, posture, and progressive strengthening. Injections may be considered for selected diagnoses after discussing benefits, limits, and risks. Surgery may be appropriate for certain fractures, recurrent instability, advanced arthritis, or tears that do not respond to conservative care.

Rehabilitation should match the diagnosis. Returning to heavy lifting or overhead activity too quickly can prolong symptoms, while excessive rest can contribute to stiffness. A staged plan can help restore movement and function safely.

Questions to ask during an evaluation

Do I need imaging now, or should we begin with conservative care?
Which movements should I modify temporarily?

What symptoms would require urgent reassessment?

Shoulder pain FAQ

Can shoulder pain improve without surgery?

Yes. Many overuse injuries, mild strains, bursitis, and some rotator cuff problems improve with activity changes and a structured rehabilitation program. The diagnosis and severity determine the plan.

Why does my shoulder hurt at night?

Night pain can occur with several shoulder conditions, including rotator cuff problems, bursitis, and arthritis. Persistent night pain should be evaluated rather than diagnosed from symptoms alone.

What type of clinician treats shoulder pain?

Primary-care clinicians, sports-medicine physicians, orthopedic specialists, and physical therapists may participate in evaluation and treatment, depending on the cause and severity.
