Arm pain is discomfort felt anywhere from the shoulder to the hand. It may come from muscles, joints, tendons, nerves, or referred pain from the neck. Symptoms can include aching, weakness, tingling, or sharp pain, and should be assessed if persistent or worsening.

Arm pain can affect lifting, gripping, reaching, computer work, sleep, sport, and everyday tasks. A physiotherapist can check your shoulder, elbow, wrist, hand, neck, and nerve function to identify the most likely driver and guide a practical treatment plan.

If your pain began after a fall, you have severe swelling, you cannot use the arm, or numbness is getting worse, seek urgent medical advice.

What causes arm pain?

Arm pain can come from local tissues such as muscles, tendons, joints, and ligaments. It can also be referred pain from the neck or upper back, especially when nerves are irritated.

Common triggers include repetitive gripping, lifting, sport, desk work, device use, poor sleep positions, and sudden overload. To support safe self-care, start by matching your symptoms to the most likely region, then book an assessment if pain persists or keeps returning.

Causes of arm pain by region

Shoulder-related arm pain

• Shoulder pain conditions
• Rotator cuff injury
• Frozen shoulder
• Shoulder bursitis
• Shoulder physiotherapy

Elbow-related arm pain

• Elbow pain conditions
• Tennis elbow
• Golfer’s elbow

Wrist and hand-related arm pain

• Wrist and hand pain conditions
• Carpal tunnel syndrome
• De Quervain’s tenosynovitis
• Wrist and hand arthritis

Can arm pain come from the neck?

Yes. A nerve irritated in the neck can refer pain into the shoulder, arm, or hand. People may notice pins and needles, numbness, weakness, or symptoms that change with neck position.

Common nerve-related causes include cervical radiculopathy, thoracic outlet syndrome, and broader nerve pain. A physiotherapist can test your neck, shoulder, arm movement, and nerve mobility to help identify the main driver.

What structures can cause arm pain?

Musculoskeletal causes

• Arthritis
• Bursitis
• Tendinopathy
• Muscle strain or overload
• Joint stiffness or irritation

Nerve-related causes

• Neck-related referred pain
• Nerve compression or irritation
• Carpal tunnel symptoms
• Thoracic outlet symptoms

How is arm pain assessed?

Arm pain assessment usually checks movement, strength, joint range, tendon load tolerance, nerve signs, and how symptoms respond to specific positions or tasks. Your physiotherapist may also assess your neck, upper back, shoulder blade control, elbow, wrist, and grip.

If your symptoms suggest a fracture, infection, inflammatory condition, or serious nerve issue, your physiotherapist may recommend GP review, imaging, or further medical assessment.

Physiotherapy for arm pain

Physiotherapy may help arm pain by identifying the likely source, reducing aggravating loads, restoring comfortable movement, and building strength for work, sport, and daily life.

A physiotherapist may recommend:

• Manual therapy: to help joint and soft tissue movement where appropriate.
• Exercise prescription: to build capacity in the shoulder, elbow, wrist, and upper back.
• Education: to guide pacing, posture, sleep positions, and safe return to lifting or sport.
• Load management: to reduce flare-ups while keeping you active.

What treatments may help arm pain?

Treatment depends on the cause, irritability, and your goals. Some people benefit from strengthening, mobility work, ergonomic changes, and activity modification. Others may use options such as dry needling as part of a broader plan.

Exercise often works best when it matches the affected region and stage. A physiotherapist may use exercise programs to progress shoulder, elbow, wrist, neck, or upper-back capacity safely.

How can you prevent arm pain from returning?

Prevention often comes down to better load management. Mix tasks, pace repetitive work, build strength gradually, and adjust desk or device setup where needed.

Small changes to ergonomics may reduce strain across the shoulder, elbow, wrist, and hand. This can be helpful for computer work, prolonged phone use, manual tasks, and repetitive gripping.

When should you get arm pain checked?

Get arm pain checked if it lasts longer than 1–2 weeks, keeps returning, affects sleep, limits work or sport, or includes numbness, tingling, or weakness. Early assessment may help clarify the cause and reduce the risk of recurring flare-ups.

What to do next

• If symptoms are mild, reduce aggravating loads for a few days and keep the arm gently moving.
• If pain lasts longer than 1–2 weeks, keeps returning, or affects work, sleep, or sport, book an assessment.
• If you have numbness, weakness, worsening night pain, or symptoms after a significant injury, get checked sooner.

Arm pain FAQs

What is the most common cause of arm pain?

Most arm pain comes from overload of muscles, tendons, or joints in the shoulder, elbow, wrist, or hand. It can also refer from the neck, especially when nerves feel irritated.

Can arm pain be caused by a pinched nerve?

Yes. A nerve can become irritated in the neck or along the arm. People often report pins and needles, numbness, weakness, or symptoms that change with neck or arm position.

When should I worry about arm pain?

Seek urgent medical care if arm pain occurs with chest pain, sudden weakness, severe swelling, fever, a hot red joint, or after a significant injury where you cannot use the arm.

Does physiotherapy help arm pain?

Physiotherapy may help by identifying the main pain driver, improving mobility and strength, and guiding a graded return to work, lifting, and sport with practical self-management strategies.

What causes arm pain at night?

Arm pain at night may relate to shoulder irritation, neck referral, nerve sensitivity, sleep position, or inflammatory joint pain. If night pain is worsening, unexplained, or linked with weakness or numbness, seek assessment.

How long should arm pain last?

Mild arm pain from overload may improve within days to a couple of weeks with sensible load changes. Pain that persists, worsens, or keeps returning should be assessed to identify the cause and guide treatment.
