Shoulder blade and arm pain left side

If you have shoulder pain, it’s often caused by problems with your shoulder joint or with the muscles, ligaments, or tendons, around your shoulder. But sometimes the source of your pain can be your heart, belly, or something else. That’s called referred shoulder pain.

Usually, if you have a shoulder problem like a pulled muscle or osteoarthritis, moving your shoulder may make the pain better or worse. But if you have referred shoulder pain, you won’t feel any difference if you move your shoulder.

Symptoms

You might notice several different kinds of pain:

  • Sharp pain under your shoulder blade
  • Dull ache in your shoulder
  • Pain that goes from your neck to your shoulder blade (or vice versa)
  • Stabbing, burning, tingling, or even an “electric” feeling in your shoulder

Referred shoulder pain is often constant, which means your shoulder will hurt even when you’re resting or not using your arm or shoulder. But it may come and go, too.

Causes

Several health problems can be behind your referred pain, including:

Heart problems, like a heart attack or angina (chest pain that happens when your heart isn’t getting enough oxygen). If you’re having a heart attack, you might also have chest pains, which you might mistake for heartburn or an upset stomach. You might also feel short of breath, or feel pain in your arm, back, jaw, neck, or other areas of your body. If that happens, call 911 right away.

Neck problems. A pinched nerve in your neck or other neck problems can cause shoulder pain.

Belly surgery. If you have laparoscopic surgery, which is done through a small cut, on your belly to remove your gallbladder, make your stomach smaller for weight loss, or for other reasons, you might get shoulder pain afterward. That happens to up to two-thirds of people who have the surgery. Laparoscopic surgery can make your body hang on to carbon dioxide in your belly area. That can irritate your spine and nerves, which can trigger shoulder pain.

Lung problems, like pneumonia or lung cancer. Tumors or swelling in your lungs may cause shoulder pain.

Blood clot in your lungs. This is called a pulmonary embolism. It can feel like a pulled shoulder muscle at first. But the pain is usually so bad that you might have a hard time lying down or sleeping. If that happens to you, call your doctor right away.

Belly problems. These include gallstones, pancreatitis (inflammation of the pancreas), an ovarian cyst, and ectopic pregnancy (a pregnancy that happens in one of your fallopian tubes). The pain caused from problems in or near your belly can move up to and between your shoulders.

Usually, you’ll also notice other symptoms, like nausea and severe pain in your belly or pelvic area. The shoulder pain and pain in other areas may come on suddenly and feel severe. If you notice these issues, call a doctor or go to the hospital.

Treatments

Your doctor will need to find out the source of your pain so they can decide how best to deal with it.

If you’ve had pain in your shoulder for more than a couple of days without an obvious reason, call your doctor. That’s especially important if you’re in a lot of pain or if you have other symptoms, like shortness of breath. Your doctor will ask about:

  • Where you feel the pain
  • How long you’ve had it, and if and when it stops
  • Your health history, including any current medical conditions like high blood pressure
  • Any accidents or injuries that could have played a part in your shoulder pain
  • Your doctor also may recommend tests to check for any hidden issues.

Ultrasound, which can give doctors a quick look at your shoulder muscles, joints, and tendons to reveal problems like rotator cuff tears.

X-rays, which can show bone problems.

MRI, which can reveal problems with your muscles, tendons, ligaments, and other tissues.

CT scan, which can show issues with your bones and some of your tendons.

Blood or other tests, especially if your doctor suspects your shoulder pain is caused by a different health problem.

Arm pain can be caused by a wide variety of problems, ranging from joint injuries to compressed nerves. Depending on the cause, arm pain can start suddenly or develop over time.

In many cases, arm pain actually originates from a problem in your neck or upper spine. Arm pain, particularly pain that radiates into your left arm, can even be a sign of a heart attack.

Seek emergency treatment if you have:

  • Arm, shoulder or back pain that comes on suddenly, is unusually severe, or is accompanied by pressure, fullness or squeezing in your chest (this may signal a heart attack)
  • An obvious deformity or protruding bone in your arm or wrist, especially if you have bleeding or other injuries

See your doctor right away if you have:

  • Arm, shoulder or back pain that occurs with any sort of exertion and is relieved by rest — possibly signaling heart disease or chest discomfort caused by reduced blood flow to your heart muscle (angina)
  • A sudden injury to your arm, particularly if you hear a snap or cracking sound
  • Severe pain and swelling in your arm
  • Trouble moving your arm normally or turning your arm from palm up to palm down and vice versa

Schedule an office visit if you have:

  • Arm pain that doesn't improve after home care
  • Increasing redness, swelling or pain in the injured area

Self-care

Even serious arm injuries can be helped initially with home treatment. If you think that you have a broken arm or wrist, apply ice packs to the affected area and use a sling to help hold your arm still until you can get medical care.

If you have a compressed nerve or repetitive strain injury, be consistent about therapy; maintain good posture; and take frequent breaks at work and during repetitive activities, such as playing an instrument or practicing your golf swing.

Most other types of arm pain will get better on their own, especially if you start R.I.C.E. measures soon after your injury.

  • Rest. Take a break from your normal activities.
  • Ice. Place an ice pack or bag of frozen peas on the sore area for 15 to 20 minutes three times a day.
  • Compression. Use a compression bandage to reduce swelling.
  • Elevation. If possible, elevate your arm to help reduce swelling.

When should I worry about left arm and shoulder pain?

Seek emergency treatment if you have: Arm, shoulder or back pain that comes on suddenly, is unusually severe, or is accompanied by pressure, fullness or squeezing in your chest (this may signal a heart attack)

Can shoulder blade pain radiate down the arm?

Shoulder pain is very common. Because they're the most mobile joints in your body, your shoulders are very prone to the effects of injuries and degenerative conditions. It's possible that shoulder pain can radiate down into your arm. Conversely, a condition affecting your upper arm may be felt around your shoulder.

When should I worry about left shoulder blade pain?

If your left shoulder blade is hurting, it could be a sign of certain heart conditions, such as pericarditis or aortic dissection. Lung cancer may further manifest as shoulder blade pain. If you have any other symptoms, such as shortness of breath, dizziness, or chest pain, seek emergency medical attention.
The main difference is how pain radiates. For men: Pain will spread to the left shoulder, down the left arm or up to the chin. For women: Pain can be much more subtle. It may travel to the left or right arm, up to the chin, shoulder blades and upper back — or to abdomen (as nausea and/or indigestion and anxiety).
