Frozen Shoulder: Symptoms, Causes, Treatment & Recovery
If you have recently noticed a persistent ache in your shoulder that makes reaching for a high shelf or putting on a coat feel impossible, you may be dealing with a common orthopedic condition. This guide explains what frozen shoulder is, what causes it, the distinct stages of recovery, and the treatments available to help you regain mobility and live without pain.
What Is Frozen Shoulder?
Your shoulder is a ball-and-socket joint surrounded by strong connective tissue known as the shoulder capsule. When you develop frozen shoulder — medically known as adhesive capsulitis — this capsule becomes thick, stiff, and inflamed.
As the tissue thickens, tight bands called adhesions develop, severely limiting shoulder movement. The natural lubricating fluid in the joint (synovial fluid) also decreases. The combination of tight tissue, inflammation, and reduced lubrication explains why even slight movement can cause significant pain.
Frozen Shoulder Symptoms
The onset of this condition is rarely sudden. Symptoms typically develop slowly, gradually affecting daily life.
- —Pain at night — Aching that worsens when lying down, often disrupting sleep.
- —Stiffness — A feeling of intense tightness deep within the joint.
- —Reduced mobility — A noticeable decrease in active and passive range of motion.
- —Difficulty lifting the arm — Routine tasks such as brushing your hair or reaching behind your back become painful or impossible.
- —Worsening over time — Pain and stiffness usually escalate over weeks or months before eventually plateauing.
What Causes Frozen Shoulder?
Orthopaedic specialists do not always identify a single trigger, but several factors are known to contribute to the condition. At its core, frozen shoulder stems from inflammation of the shoulder capsule.
- —Diabetes — People with diabetes face a significantly higher risk, likely due to the effect of elevated glucose levels on collagen in the joints.
- —Injury or trauma — A previous shoulder injury, such as a rotator cuff tear, can trigger internal inflammation.
- —Surgery — Recovery from shoulder, chest, or breast surgery can cause the capsule tissue to stiffen.
- —Prolonged immobilisation — Keeping the arm in a sling for an extended period following a fracture or stroke prevents natural movement and leads to stiffness.
- —Hormonal changes — Hormonal fluctuations in women over 40 play a significant role in joint health and susceptibility to this condition.
Frozen Shoulder and Menopause
There is a well-documented connection between frozen shoulder and menopause. Women account for up to 70% of adhesive capsulitis cases.
During menopause, hormonal changes affect how the body regulates tissue health. The decline in oestrogen directly influences joint inflammation, as oestrogen naturally helps protect joints and regulate systemic inflammation. As levels drop, joints become more vulnerable to stiffness, swelling, and the development of adhesions. This helps explain why women entering or going through menopause are significantly more affected by this condition than men of the same age.
The 4 Stages of Frozen Shoulder
—Freezing Stage
The most painful phase. Any shoulder movement causes intense aching, and the range of motion begins to decline. This stage typically lasts from six weeks to nine months.
—Frozen Stage
Intense pain may ease slightly, but stiffness reaches its peak. Daily tasks involving the arm become very difficult. This stage typically lasts four to six months.
—Thawing Stage
The range of motion slowly begins to return. Stiffness starts to loosen, and arm movement gradually improves.
—Recovery Stage
Mobility steadily returns to normal, or near normal. Pain resolves and shoulder strength is gradually restored through continued use and rehabilitation.
Frozen Shoulder Treatment Options
The right treatment depends on the severity of your symptoms and the stage you are currently in.
- —Anti-inflammatory medication — Over-the-counter NSAIDs such as ibuprofen help reduce pain and inflammation, particularly during the freezing stage.
- —Physical therapy — A physical therapist guides you through stretching and mobility exercises to keep the joint as functional as possible throughout recovery.
- —Corticosteroid injections — An injection directly into the shoulder joint reduces severe inflammation, particularly effective in the early stages.
- —Hydrodilatation — A specialist injects sterile fluid into the joint to gently stretch and expand the tight shoulder capsule.
- —Surgery — When non-surgical methods fail to provide relief after a prolonged period, surgical intervention may be considered.
Exercises for Frozen Shoulder
Gentle, consistent movement is essential. Before attempting these exercises, warm up the shoulder with a warm, moist towel or a warm shower. Always move to the point of tension — never into sharp pain.
- —Pendulum stretch — Lean forward slightly, let the affected arm hang freely, and swing it in small circles.
- —Towel stretch — Hold a towel vertically behind your back with both hands and use the healthy arm to gently pull the affected arm upward.
- —Finger walk — Stand facing a wall at arm's length and slowly walk your fingers up the surface to raise your arm.
- —Cross-body reach — Use your unaffected arm to gently draw the affected arm across your chest until you feel a stretch.
- —Wall slide — Stand beside a wall and slowly slide your hand upward to gradually increase your reaching range.
When Is Surgery Needed?
Most patients recover without surgery. Surgical intervention is considered when severe stiffness fails to improve after 12 to 18 months of thorough conservative treatment. Two main approaches are used.
- —Manipulation under anaesthesia — While the patient is asleep, the doctor moves the shoulder to break through the tight capsule tissue and release the joint.
- —Arthroscopic capsular release — Small incisions allow the surgeon to cut through the tightest portions of the shoulder capsule using fine instruments, restoring mobility.
When to See an Orthopaedic Specialist
Do not ignore persistent shoulder pain. If any of the following apply, schedule an evaluation to receive an accurate diagnosis and prevent the condition from progressing further.
- —Symptoms continue for more than a few weeks or worsen at night
- —Significant restriction in shoulder movement affecting daily activities
- —No improvement with rest and over-the-counter pain relief
- —Weakness in the arm or inability to lift it comfortably
- —Pain that disrupts sleep regularly
