Read on to learn more about possible causes of arm pain and how to treat them.
Injuries
Arm pain may arise from various injuries, including:
- a broken bone or fracture
- a dislocated elbow
- laceration
- bruising
- a strained or torn muscle
Treatments
Some minor arm injuries, such as strains or bruising, will resolve with at-home treatments, including adequate rest, ice, and over-the-counter (OTC) pain medications. More serious injuries, such as a dislocated elbow or a fracture, may require medical interventions, including physical therapy or surgery.
Infections
Arm pain can also be the result of various infections, including:
- cellulitis, which is a bacterial skin infection that can also cause redness and swelling
- osteomyelitis, which is an acute or chronic bone infection
- septic arthritis, which is a form of arthritis resulting from an infection
Treatments
Doctors will typically treat infections with antibiotics. Severe cases of osteomyelitis may require surgical draining and cleaning of the infected area or a bone graft. Septic arthritis treatment may also involve joint drainage.
Degenerative conditions
Certain degenerative conditions may cause arm pain. Cervical spondylosis, for example, occurs when the discs in your spine begin to wear down, resulting in pain that can radiate to your arms. It is a very common condition in people over the age of 60 years.
Osteoarthritis is another degenerative condition that can cause arm pain. It occurs when the cartilage around your joints wears down, causing pain and stiffness. According to the
Treatments
Treatment for degenerative conditions often involves medications and physical therapy. Surgery may be necessary if other treatments are ineffective or if you are experiencing severe complications.
Inflammatory conditions
Conditions that cause inflammation can affect the arm and cause pain. These may include:
- bursitis, or inflammation of the fluid filled sacs that cushion your joints
- rheumatoid arthritis, which is a chronic autoimmune condition that causes joint inflammation
- tendinitis, or inflammation of a tendon
Treatments
Some inflammatory conditions arise due to repetitive motions or overuse. In these cases, you may need to avoid the activity or motion that caused the condition. You may also be able to treat mild inflammatory conditions at home with rest, ice, OTC pain medications, and gentle stretches and exercises.
More serious inflammatory conditions, such as rheumatoid arthritis, will need medical treatment. Your doctor
Nerve conditions
Arm pain can result from several conditions that affect your nerves, including:
- carpal tunnel syndrome, which is a condition involving a pinched nerve in the wrist
- cervical spinal stenosis, which is a narrowing of the spinal canal with compression of the spinal cord and nerves in the neck
- cervical radiculopathy, which is a condition wherein a nerve in your neck is pinched or irritated
Treatments
Treatment for nerve conditions can involve medications and physical therapy. Your doctor may also recommend wearing immobilization devices to help prevent further nerve damage while you are undergoing treatment. For example, people with carpal tunnel syndrome may need to wear a brace to keep their wrists in a neutral position.
If initial treatments are ineffective, your doctor may recommend surgery.
Heart attack
Pain that radiates to one or both arms is a common symptom of a heart attack. It may occur with a feeling of pressure or a squeezing pain in the center of the chest.
Seek emergency medical care (call 911) if you have pain in one or both arms along with any of these other symptoms:
- nausea
- vomiting
- sweating
- an irregular heart rate
- difficulty breathing

In the short term, treatment for a heart attack
Other causes
Some other causes of arm pain may include:
- Bone tumors: Both malignant and benign bone tumors can cause arm pain or discomfort. Malignant bone tumors may require surgical removal, chemotherapy, or radiation therapy. In some cases, doctors may decide to monitor a benign bone tumor. In other cases, they may remove it or treat it with medications.
- Complex regional pain syndrome (CRPS): People with an arm injury may experience pain that is disproportionate to the injury. Although most cases of CRPS resolve on their own, some people may require extensive physical therapy, medications, and other medical procedures.
- Vaccinations: Many vaccinations can cause general arm pain or pain at the injection site. OTC pain medications and gentle arm movements may help relieve the pain.
What other symptoms might occur with arm pain?
Other symptoms may occur with arm pain and can vary depending on the underlying disease, disorder, or condition. These symptoms can include:
- back, neck, or shoulder pain
- a burning sensation
- difficulty sleeping
- flu-like symptoms
- joint pain
- muscle spasms
- numbness
- reduced elbow movement
- skin bumps
- skin discoloration, such as bruising

What are some potential complications of arm pain?
Because arm pain can result from serious conditions, not seeking treatment may lead to complications or permanent damage. It is important to seek medical treatment when you experience persistent pain or other unusual symptoms.
Once your doctor has diagnosed the underlying cause, following their treatment plan can lower your risk of potential complications, including:
- arm disability
- chronic pain
- amputation
- a loss of strength
- permanent nerve damage
- the spread of infection
When should you contact your doctor about arm pain?
If you are experiencing persistent or recurring arm pain, contact your doctor to rule out any serious injuries or underlying conditions. In some cases, arm pain may occur with other symptoms that might indicate a serious or life threatening condition that requires immediate evaluation in an emergency setting.
Seek immediate medical care (call 911) if you have arm pain with other serious symptoms, including:
- arm deformity
- bluish coloration of the lips or fingernails
- a change in your level of consciousness or alertness
- confusion
- a fever higher than 101ºF (38.3ºC)
- an inability to use your arm

Frequently asked questions
Here are a few other commonly asked questions about arm pain. Dr. Angela Bell has reviewed the answers.
How do you know if you have a pinched nerve in your arm?
A pinched nerve in your arm can cause pain, numbness, or a tingling sensation similar to pins and needles. Doctors will typically be able to tell if you have a pinched nerve based on your symptoms and the results of a physical examination. Imaging and nerve testing can confirm the diagnosis.
Can stress cause pain in your arm?
Stress can cause arm pain. Stress and anxiety may cause your muscles to become tense, resulting in pain.
What does cardiac arm pain feel like?
Arm pain that results from a cardiac event can be sudden and severe. It may radiate down the arm or up toward the neck and chin. If you experience arm pain along with symptoms such as chest pain or tightness, seek medical help immediately.
Summary
Various conditions — including injuries, infections, and other disorders — can cause arm pain. Although some cases of arm pain may resolve on their own or with at-home treatments, others will need medical intervention.
Talk with your doctor if you are experiencing arm pain. They can help determine the cause and a proper treatment plan.
