Why Is My Shoulder Pain Worse At Night?

Shoulder pain is one of the most common musculoskeletal conditions we see at Elite Joint Solutions. A frequent question patients ask is:

"Why does my shoulder feel much worse at night than it does during the day?"

If you've found yourself struggling to get comfortable in bed, waking up multiple times throughout the night, or needing to constantly reposition yourself because of shoulder pain, you're certainly not alone.

The good news is that there are several explanations for why shoulder pain tends to worsen at night, and understanding the underlying cause can help guide effective treatment.

Why Does Shoulder Pain Get Worse At Night?

There are several theories as to why shoulder pain becomes more noticeable at night.

Firstly, during the daytime we are constantly distracted by work, exercise, hobbies and everyday activities. When we finally settle down in bed, there are fewer distractions and our brains become much more aware of pain signals coming from the shoulder.

Secondly, blood flow to inflamed tissues can increase when lying down. This can contribute to a build-up of inflammatory chemicals within the shoulder, making symptoms more noticeable.

Finally, sleeping positions can place additional pressure on already irritated structures within the shoulder joint. Sleeping directly on the painful shoulder is often particularly uncomfortable and may aggravate symptoms further.

Rotator Cuff Tendinopathy

One of the most common causes of night-time shoulder pain is rotator cuff tendinopathy.

The rotator cuff is a group of four muscles and tendons that help stabilise and move the shoulder joint. Over time these tendons can become overloaded, degenerate or develop small tears.

Common symptoms include:

• Pain when lifting the arm

• Difficulty reaching overhead

• Pain putting on a coat

• Pain reaching behind the back

• Night-time shoulder pain

• Difficulty sleeping on the affected side

Many patients find that lying on the affected shoulder compresses the already irritated tendon, causing significant discomfort.

Shoulder Bursitis

The shoulder contains a small fluid-filled sac called the bursa. The purpose of the bursa is to reduce friction between tissues as the shoulder moves.

When the bursa becomes inflamed, a condition known as bursitis develops.

Symptoms often include:

• Sharp pain when lifting the arm

• Painful arc of movement

• Pain when lying on the affected shoulder

• Night pain

• Difficulty sleeping

Bursitis commonly occurs alongside rotator cuff tendinopathy and the two conditions frequently coexist.

Frozen Shoulder

Frozen shoulder (adhesive capsulitis) is another common cause of severe night pain.

The condition occurs when the capsule surrounding the shoulder joint becomes inflamed and tightens.

Patients commonly report:

• Severe night pain

• Progressive stiffness

• Difficulty reaching overhead

• Difficulty fastening a bra or reaching behind the back

• Pain when turning over in bed

Night pain during the early inflammatory phase can be particularly severe and often has a significant impact on sleep quality.

Shoulder Arthritis

As we age, the cartilage within the shoulder joint can gradually wear down, leading to arthritis.

Common symptoms include:

• Deep aching pain

• Stiffness

• Grinding sensations

• Reduced movement

• Night-time discomfort

Arthritic joints often become stiff during periods of inactivity, which is one reason symptoms may feel worse overnight.

What Can I Do To Reduce Shoulder Pain At Night?

There are several simple measures that may help:

Sleep Position

Try avoiding sleeping directly on the painful shoulder.

Many patients find relief by:

• Sleeping on their back

• Sleeping on the opposite side

• Placing a pillow under the affected arm for support

Ice Or Heat

Some patients prefer ice whilst others respond better to heat.

Generally:

• Ice may help if the shoulder feels inflamed

• Heat may help if the shoulder feels stiff

Gentle Exercises

Maintaining shoulder mobility is important.

Gentle range-of-motion exercises can often help reduce stiffness and improve comfort.

Over-The-Counter Medication

Simple pain relief such as paracetamol or anti-inflammatory medications may be appropriate for some individuals.

Always seek advice from your pharmacist or healthcare professional before starting medication. If this is not helping you could consider prescribed medication. To discuss this please contact us: https://www.elitejointsolutions.com/

When Should I Seek Professional Help?

You should consider seeking professional advice if:

• Pain persists for more than 6 weeks

• Sleep is regularly disturbed

• Shoulder movement is becoming restricted

• Symptoms are worsening

• You have significant weakness in the arm

Early diagnosis often leads to quicker recovery and may prevent symptoms becoming chronic.
