What Is Biceps Tendinopathy?

Biceps tendinopathy is an umbrella term describing irritation, overload, or degeneration of the biceps tendon. Although many people still use “tendonitis”, clinicians now prefer “tendinopathy” because tendon change is often present without ongoing inflammation.

• Biceps tendonitis – more reactive or irritated presentations
• Biceps tendinosis – degenerative tendon change
• Biceps tenosynovitis – irritation around the tendon sheath
• Partial or complete rupture – tearing, often linked with degeneration

Where Is the Biceps Tendon and Why Does It Get Sore?

The biceps brachii has two heads: short and long. The long head runs through the front of the shoulder and attaches near the top of the shoulder socket. It contributes to shoulder stability, particularly during arm elevation and load-bearing tasks.

Because this tendon works closely with the rotator cuff, it often becomes painful when shoulder control, strength, or load tolerance drops. Research shows long head of biceps tendon problems frequently occur alongside rotator cuff pathology. 1,2

Common Causes and Risk Factors

Biceps tendinopathy rarely occurs in isolation. It often presents alongside rotator cuff tears or shoulder instability. 1,2

• Sudden training increases or workload spikes
• Repeated overhead lifting or reaching
• Poor shoulder blade control during pressing or pulling
• Throwing, swimming, gymnastics, contact or racquet sports
• Upper back or neck stiffness affecting shoulder mechanics

A tailored physiotherapy plan can align rehabilitation with your work or sporting demands.

Symptoms of Biceps Tendinopathy

• Pain at the front of the shoulder, sometimes into the upper arm
• Discomfort with lifting, pulling, or pushing
• Pain with elbow bending or forearm rotation
• Clicking or snapping sensations in some cases
• Night pain, especially when side-sleeping

Assessment and Diagnosis

A physiotherapist assesses shoulder movement, strength, tendon sensitivity, and shoulder blade control. The neck is also screened, as neck-related pain can mimic shoulder symptoms.

Ultrasound or MRI may assist when symptoms persist, multiple structures are involved, or a tear is suspected. Imaging alone does not always explain pain severity. 3

Treatment for Biceps Tendinopathy

Physiotherapy typically focuses on settling pain drivers and rebuilding tendon and shoulder capacity. Evidence supports a multimodal approach using load management, exercise-based rehabilitation, and addressing contributing factors across the shoulder complex. 3,4

1) Load management

Early management involves reducing movements that spike pain while keeping the shoulder active within comfortable limits.

• Temporary activity modification
• Ice or heat for symptom relief
• Sleep positioning support
• Strapping or taping when helpful

2) Strength and control

Exercise commonly includes scapular control, rotator cuff strengthening, and graded biceps loading. 3,4

• Isometric loading
• Slow resistance training
• Sport- or work-specific loading

See rotator cuff exercises for examples.

3) Address related shoulder issues

• Rotator cuff tendinopathy
• Shoulder impingement
• Rotator cuff tear

4) Neck and upper back contributors

Neck or upper back stiffness can influence shoulder control. Treating these regions may support shoulder rehabilitation.

5) Injections and surgery

Some people consider injections for short-term symptom relief. Long-term improvement often relies on restoring load tolerance. In cases of significant tearing or persistent symptoms, surgical options may be discussed. 5

What to do next

If shoulder pain is limiting your work, training, or sleep, book a physiotherapy assessment. A physiotherapist can confirm whether the biceps tendon is the main driver and outline the next steps.
