What are the potential causes of chest pain that radiates to the arm?
Chest pain that radiates to your arm is a classic warning sign of a heart-related problem, such as a heart attack or angina. However, non-cardiac conditions like muscle strain, nerve compression, or acid reflux can also produce similar symptoms.
Key causes of chest pain radiating to the arm:
- Heart attack: Reduced blood flow to the heart muscle
- Angina: Temporary lack of oxygen to the heart
- Musculoskeletal pain: Strained chest or shoulder muscles
- Nerve-related pain: Pinched nerves in the neck or spine
- Digestive issues: Acid reflux or esophageal spasms
Because the causes range from life-threatening to relatively minor, identifying the source of your pain quickly is critical. If you're experiencing sudden, severe, or unexplained chest pain, seek emergency care immediately.
For non-emergency symptoms, the smartest next step is to take a free, instant, online symptom check. It takes just a few minutes, uses AI trained on medical data, and helps you understand possible causes and which type of doctor to see next—so you can move forward with clarity instead of guesswork.

When you feel chest pain that travels to your arm, one common reason is that your heart might not be receiving enough blood. This can happen during a heart attack or when you have angina, which means your heart muscle is not getting the oxygen it needs, especially during effort or stress. This type of pain is taken very seriously by doctors. Sometimes, pain may also come from other areas like the muscles or nerves, but when it moves from your chest to your arm—particularly the left arm—it is usually a sign to check your heart first. To find out the exact cause, your doctor might do tests such as an electrocardiogram (EKG), blood tests, or imaging studies. If you experience chest pain that spreads to your arm along with other signs like shortness of breath, sweating, or feeling very weak or dizzy, you should get help immediately. You can also use Ubie's free AI-powered symptom checker to help understand your symptoms before speaking with a healthcare provider, but it is always best to have any chest pain evaluated by a doctor right away to make sure your heart is healthy and to get the right treatment if needed.
