You finally settle into bed after a long day, only to find yourself struggling to get comfortable. Maybe you can’t lie on your favorite side, or an aching sensation wakes you up every time you roll over.
Sound familiar?
If you’ve ever wondered, “Why does my shoulder hurt at night?” you’re not alone. While occasional discomfort may result from overuse or an awkward sleeping position, ongoing symptoms could point to an underlying orthopedic condition.
At Texas Orthopaedic Associates, our experienced physicians help patients throughout Dallas-Fort Worth identify the source of their discomfort and explore treatment options to restore mobility, improve sleep, and get back to the activities they enjoy.
Here are five common conditions that could be responsible for those restless nights.
1. Rotator Cuff Injuries
Your rotator cuff consists of four muscles and their tendons that stabilize the joint and allow you to lift and rotate your arm. Over time, these tendons can become irritated or torn due to repetitive movements, aging, or an injury.
Common symptoms include:
- Discomfort that worsens when lying on the affected side
- Difficulty lifting your arm overhead
- Weakness when reaching or carrying objects
- Trouble reaching behind your back
- Aching that interrupts your sleep
Rotator cuff problems are particularly common among individuals who participate in activities involving repetitive arm movements, such as golf, tennis, swimming, and weightlifting.
Do rotator cuff injuries always require surgery?
Not necessarily. Many conditions can be managed through physical therapy, activity modification, medications, or injections. More significant tears may require surgical treatment depending on the severity and individual needs.
2. Bursitis
If lying down or performing certain movements causes discomfort, bursitis could be responsible.
Bursae are small, fluid-filled sacs that cushion the bones, muscles, and tendons around your joints. When these structures become irritated or inflamed, they can cause tenderness and restricted movement.
Signs of bursitis may include:
- Aching along the outside of the upper arm
- Tenderness when lying on the affected side
- Difficulty lifting your arm
- Discomfort during repetitive overhead activities
Bursitis can develop from repetitive movements, overuse, or other joint conditions.
Treatment often begins with modifying activities, physical therapy, anti-inflammatory medications when appropriate, and occasionally corticosteroid injections.
3. Arthritis
While arthritis is commonly associated with the knees and hips, it can also affect the upper body.
Shoulder arthritis occurs when the cartilage cushioning the joint gradually wears down, leading to stiffness, inflammation, and reduced mobility.
For some individuals, symptoms become especially noticeable after a busy day or during periods of rest.
Common signs include:
- Deep, persistent aching
- Stiffness after periods of inactivity
- Grinding or clicking sensations
- Difficulty reaching overhead
- Reduced range of motion
Arthritis becomes more common with age, although previous injuries and repetitive stress may also contribute.
Depending on the severity, treatment may include physical therapy, medications, injections, or joint replacement for advanced cases.
4. Frozen Shoulder (Adhesive Capsulitis)
Have you noticed increasing stiffness or difficulty moving your arm?
You may be experiencing a condition called frozen shoulder, also known as adhesive capsulitis.
This condition develops when the tissues surrounding the joint become thickened and tight, restricting movement.
Symptoms often include:
- Discomfort that becomes more noticeable at bedtime
- Increasing stiffness over time
- Difficulty reaching overhead
- Trouble getting dressed
- Limited movement, even with assistance
Frozen shoulder commonly affects adults between the ages of 40 and 60 and is more prevalent among individuals with diabetes or certain thyroid conditions.
Treatment focuses on managing discomfort and gradually restoring movement through stretching, physical therapy, medications, and sometimes injections or other procedures.
5. Tendonitis
Tendonitis occurs when a tendon becomes irritated, often from repetitive activity or overuse.
Whether you’re spending weekends on the golf course, playing pickleball, working in the yard, or lifting weights, repeated movements can contribute to tendon problems.
Common symptoms include:
- Discomfort when lifting or rotating your arm
- Tenderness around the joint
- Aching after physical activity
- Difficulty lying on the affected side
- Trouble completing everyday tasks
Many cases improve with conservative care, including physical therapy, activity modification, and appropriate medications.
However, persistent symptoms should be evaluated to rule out more significant tendon damage.
Why Is the Discomfort Worse When You’re Trying to Sleep?
You might feel relatively comfortable during the day, only to experience aching or stiffness once you settle into bed.
Several factors can explain this.
Sleeping position: Lying directly on an irritated joint places additional pressure on sensitive tissues.
Reduced movement: Staying in one position for extended periods can make stiffness more noticeable.
Inflammation: Inflamed tendons, bursae, or joints may become uncomfortable in certain resting positions.
Fewer distractions: During the day, work and other activities occupy your attention. At bedtime, physical discomfort may become more noticeable.
Changing your sleeping position may provide temporary relief, but recurring symptoms deserve attention.
Tips for Getting a Better Night’s Sleep
A few simple adjustments may help you rest more comfortably while you determine what’s causing the problem.
- Change your sleeping position. Try resting on your back or opposite side.
- Support your arm with a pillow. Proper positioning may reduce strain on sensitive tissues.
- Try ice or gentle heat. Cold may help reduce inflammation, while warmth can relieve stiffness.
- Limit aggravating activities before bedtime. Heavy lifting and repetitive overhead movements may increase discomfort.
- Ask about appropriate pain relief. Your healthcare provider can recommend medications or other treatments based on your medical history.
These strategies may offer temporary relief but won’t necessarily resolve the underlying condition.
When Is It Time to See an Orthopedic Specialist?
Occasional soreness after exercise or physical activity isn’t unusual. However, certain symptoms suggest it’s time to seek professional care.
Consider scheduling an evaluation if you experience:
- Discomfort that repeatedly interrupts your sleep
- Symptoms that persist or worsen despite rest
- Difficulty lifting your arm or reaching overhead
- Weakness in your arm
- Stiffness that limits everyday activities
- Trouble working, exercising, or completing routine tasks
Seek immediate medical attention for severe symptoms following an injury, obvious deformity, or sudden inability to move your arm. Discomfort accompanied by chest pain, shortness of breath, or sweating may be a medical emergency.
Seeing an orthopedic surgeon doesn’t automatically mean you’ll need surgery.
Many conditions can be managed with non-surgical treatments, particularly when identified and addressed appropriately.
