Why Does My Shoulder Hurt at Night?

Shoulder Pain Keeping You Awake?

Shoulder pain that gets worse at night is one of the most common reasons people seek physical therapy. Many patients tell us they can get through the day, but as soon as they lie down, their shoulder begins to ache.

The good news? Most nighttime shoulder pain can be treated without surgery.

Why Does It Hurt More at Night?

When you're standing, gravity helps position your shoulder. Once you lie down, pressure on the joint and surrounding tissues changes. Inflamed tendons, muscles, or the joint itself can become more sensitive, making pain more noticeable while trying to sleep.

Common Causes

Rotator Cuff Tendinitis

Inflammation of the rotator cuff tendons is one of the leading causes of nighttime shoulder pain. Reaching overhead or lifting objects often makes symptoms worse.

Shoulder Impingement

When the tendons become compressed during movement, inflammation develops and can become especially painful at night.

Arthritis

Shoulder arthritis may cause a deep aching pain, stiffness, and difficulty finding a comfortable sleeping position.

Sleeping Position

Sleeping directly on the painful shoulder or with your arm overhead may increase pressure on irritated tissues.

Referred Pain

Sometimes neck problems can create pain that feels like it's coming from the shoulder.

How Physical Therapy Can Help

At Apex Physical Therapy & Wellness, we focus on treating the cause of your pain—not just the symptoms.

Treatment may include:

• Restoring shoulder mobility

• Strengthening the rotator cuff

• Improving shoulder blade mechanics

• Manual therapy

• Activity and sleep-position education

Most patients begin noticing improvement within a few weeks.

Tips for Better Sleep

If your shoulder hurts at night, try:

• Sleeping on your back or your non-painful side

• Placing a pillow under your arm for support

• Avoiding sleeping with your arm overhead

• Applying ice before bed if recommended by your therapist

Small changes in sleeping position can significantly reduce irritation.

When Should You See a Physical Therapist?

Schedule an evaluation if:

• Pain wakes you up at night

• Symptoms last longer than two weeks

• You have difficulty lifting your arm

• Shoulder pain limits work, golf, pickleball, or daily activities

Early treatment often leads to a faster recovery and may help you avoid injections or surgery.
