Does your shoulder blade hurt? You're not alone. People of all ages can experience an ache.

The discomfort can range from a mild ache to a sharp, stabbing pain that makes everyday tasks, such as reaching for your phone or carrying groceries, difficult. It can be due to a minor muscle strain from hunching over a laptop for long hours, lifting heavy objects, or sleeping in an awkward position. 

Your muscles are one of the major joints, connected to your collarbone and upper arms, and surrounded by many muscles, tendons, and nerves. Because so many parts of the body meet in this area, the discomfort may not always be caused by a simple muscle strain.

Sometimes, a shoulder blade ache can be a sign of an underlying health condition. Problems related to the neck, lungs, heart, or even the digestive system can sometimes cause pain in this area. While a shoulder blade ache is usually not serious, you should consult a doctor if it is severe, lasts for a long time, or is accompanied by other symptoms, as it could indicate a more serious condition.

Understanding Shoulder Blade Pain

Most often, shoulder blade pain is due to muscle strain, poor body alignment, or overuse, though sometimes the origin is elsewhere in the body. For example, a pinched nerve in the neck may cause a sharp and stinging ache in the shoulder blade. In a few instances, it could be a hidden health condition. Rest, ice, gentle stretching, and avoiding activities that aggravate the pain usually help with a mild ache. However, if it is associated with chest pressure, difficulty breathing, dizziness, or unusual discomfort, it is serious and must be treated as such. Immediately seek medical assistance.

10 Common Causes of Shoulder Blade Pain

You may be surprised at how often shoulder blade tingle actually occurs and how many different factors can lead to it. While a lot of the time it's a minor muscle issue, other times it can point to a more serious problem. Knowing the possible sources of the pain can help you relieve it or seek medical care if you need it. Below, we will look at its 10 common causes:

1. Poor Posture:

 One of the most common causes of shoulder blade pain is a poor sitting position, since many people spend their time:  

• Working on a laptop for a very long period of time.

• Using a smartphone while looking down continuously.

• Driving for a longer period of time without resting.

• Sitting without taking a back support.

Over time, poor sitting positions place extra stress on the muscles around the shoulder blades and upper back.

Symptoms

• Ache between the shoulder blades

• Stiffness in the upper back

• Neck tension

• Ache that worsens after sitting

Treatment

• Improve sitting position

• Use ergonomic furniture

• Take regular stretching breaks

• Strengthen back muscles

2. Strain or Overuse of muscles.

Many people experience shoulder blade pain after pushing themselves too hard during workouts or gym sessions.

The muscles can become overstrained during these activities, such as:

• Heavy lifting in normal life activities

• Intense workouts in the gym

• Carrying heavy bags

• Doing the same arm movements in the daily routine

• Muscle strain can lead to inflammation and soreness around the shoulder blades.

Symptoms

• Your muscles hurt and are tender.

• They will hurt when moved.

•  You have involuntary muscle spasms.

• You can't stretch your muscles as far as you used to.

Treatment

• Rest: Allow that muscle to rest!

• Ice:  Over the strained area, apply an ice pack for 15-20 minutes at a time, several times a day.

• Stretching:  Once pain has eased, extend the affected muscles gently after a few minutes.

• Physical therapy:  A physical therapist is available, if needed, for more severe cases, to assist people with getting back to their regular activities.

3. Neck Problems

Your neck and shoulder blades are closely connected. Problems in the neck, such as cervical spondylosis, a slipped disc, or a pinched nerve, can cause pain that travels from the neck to the shoulder blades.

Common Problems 

• Cervical spondylosis

• Herniated discs

• Pinched nerves

Symptoms

• Neck tingle

• Headaches

• Tingling in arms

• Shoulder blade discomfort

4. Rotator Cuff Injuries

So what exactly is the rotator cuff? It's essentially a group of muscles and tendons that form a cuff around your shoulder joint, acting to hold it all together.

How do we get injured? Well, it's the usual suspects:

• Sports

•  Doing the same thing over and over again

• Just getting old

• Tripping and falling 

Symptoms

• Having a weak shoulder

• Difficulty raising the arm

• Discomfort around the shoulder blade

• Clicking sounds during movement

Treatment

• Take some time to relax!

• Do some physiotherapy

• You can also take anti-inflammatory medicines.

• If it's very serious, surgery might be an option.

• Some stretching exercises will help.

• Go to a physical therapist.

5. Herniated Disc

A herniated disc occurs when the soft center of a spinal disc pushes out through a tear in the stiff outer disc. It creates pressure on nerves close to the disc, leading to pain, numbness, or weakness.

Symptoms

• Chronic neck or upper back pain

•  that travels to the shoulder blade, arm, or hand

• Tingling or "pins and needles" sensation in the arm or fingers

• Numbness of the shoulder, arm, or hand

• Arm or hand muscle weakness

Treatment 

• Rest and Activity Modification

• Physical Therapy

• Medications

• Hot/Cold Therapy

• Stretching exercises. 

6. Pain in the left shoulder blade

A large number of people state that it is specifically under the left shoulder blade that they experience pain.

This may be due to

• Rib dysfunction

• Nerve irritation

• Digestive issues

• Common Characteristics

• Burning sensation

• Pain with deep breathing.

7. Arthritis

Arthritis can affect the shoulder and upper spinal joints, leading to persistent discomfort.

Common types include

• Osteoarthritis

• Rheumatoid arthritis

It is often caused by inflammation around the shoulder blade area.

Symptoms

• Joint stiffness

• Swelling

• Reduced mobility

• Persistent discomfort

Treatment Options

• Exercise

• Weight management

• Physical therapy

8. Frozen Shoulder

Frozen shoulder is a condition that causes the tissue that surrounds the shoulder joint to become thickened and stiff. This causes pain and restricts movement in the arm. The condition develops gradually over time.

Symptoms

• Difficulty moving the arm

• Discomfort in the arm when lifting

• Trouble reaching behind your back

• Night-time ache

Treatment

• Physiotherapy

• Stiffness heating packs

• Medicines for pain relief

• Do Not Lift Heavy Objects

• Surgery is used only in rare cases

9. Spinal Curvature

This condition involves a sideways curve in the spine, which leads to an imbalance in muscles on either side of the body. Because of this imbalance, you might notice that one shoulder blade sticks out further than the other, leading to ongoing tension and tiredness.

Symptoms

• One shoulder is higher than the other, or more of your shoulder blade is sticking out.

• A consistent soreness in one part of your upper back.

• Your muscles will get tired quickly when you stand or sit tall.

• The pain you feel just gets worse throughout the day.

Treatment

• Physical therapy focused on strengthening core and back muscles.

• Wearing a brace as an adolescent to stop the curvature from worsening.

• Training for awareness of one's Body position.

•  Surgery to fix severe curvature.

10. Heart Lining Inflammation

That ache might be coming from your heart. Inflammation of the sac around your heart can trigger pain that radiates to your neck and shoulders. This condition is frequently caused by viruses, autoimmune diseases, or surgery on the heart.

Symptoms

•  A sudden, sharp pain in your chest, which gets worse when you lie down.

•   that goes to your shoulder blades (both or just one side).

• It helps to feel better if you sit up and lean forward.

• You may have a slight fever and difficulty breathing.

Treatment

• See a doctor immediately and have an ECG (electrocardiogram).

•  You'll be given anti-inflammatory drugs such as NSAIDs (non-steroidal anti-inflammatory drugs) or colchicine.

• The underlying cause (a viral infection or autoimmune disease) will need to be treated.

•  Rest and avoid heavy physical activity.
