Biceps Tendonitis: Causes, Symptoms & Treatment Options

Biceps tendonitis is inflammation or irritation of the tendon that connects the biceps muscle to the shoulder. It is a common cause of pain at the front of the shoulder, especially in people who perform repetitive overhead activities or lifting. Early diagnosis and treatment can relieve pain and prevent the condition from worsening.

What Is Biceps Tendonitis?

The biceps muscle has two tendons at the shoulder: the long head and the short head. Biceps tendonitis usually affects the long head tendon, which runs through a groove at the front of the shoulder. Overuse, ageing, or injury can cause this tendon to become inflamed, thickened, or frayed, leading to pain and weakness.

Common Symptoms

    • Aching or sharp pain at the front of the shoulder
    • Pain that worsens with lifting or overhead movements
    • Tenderness over the biceps groove at the front of the shoulder
  • Clicking or catching sensation with movement
  • Weakness in lifting or rotating the arm

Causes and Risk Factors

  • Repetitive overhead activities (tennis, swimming, weightlifting)
  • Occupations involving heavy lifting or overhead work
  • Age-related wear and tear of the tendon
  • Previous shoulder injuries such as rotator cuff tears or instability
  • Inflammatory conditions such as shoulder impingement or arthritis

How Is Biceps Tendonitis Diagnosed?

Diagnosis is based on clinical examination and imaging if required:

  • Physical exam: Tenderness in the bicipital groove, pain with resisted elbow flexion or supination
  • Ultrasound: Shows tendon inflammation, thickening, or tears
  • MRI: Detects associated shoulder problems such as rotator cuff tears or labral injuries

Treatment Options

Non-Surgical Management

  • Rest and activity modification
  • Anti-inflammatory medications (NSAIDs)
  • Physiotherapy to strengthen shoulder and rotator cuff muscles
  • Corticosteroid injections for persistent pain
  • Ice therapy and supportive taping

Surgical Treatment

Surgery may be recommended if symptoms persist after months of non-surgical care, or if the tendon is severely damaged. Options include:

  • Biceps tenotomy: Cutting the tendon to relieve pain (often used in older or low-demand patients)
  • Biceps tenodesis: Reattaching the tendon to the upper arm bone (preferred for younger, active patients)
  • Often performed arthroscopically (keyhole surgery) alongside treatment for other shoulder conditions

Recovery and Return to Activity

  • Most patients improve with non-surgical care in 6–12 weeks
  • After surgery, sling support may be required for 2–4 weeks
  • Physiotherapy focuses on restoring range of motion and strength
  • Return to desk work: 1–2 weeks after surgery
  • Return to heavy work or sport: 3–4 months, depending on the procedure

When to See a Shoulder Specialist

If you have persistent shoulder pain at the front of your shoulder that does not improve with rest and physiotherapy, it is important to see a shoulder surgeon. Early treatment prevents tendon damage and improves recovery outcomes.

Frequently Asked Questions

How long does biceps tendonitis take to heal?
Most cases settle with rest, activity modification and physiotherapy over about 6–12 weeks. More stubborn cases, or those that need surgery, can take 3–4 months to recover fully.
Will biceps tendonitis go away on its own?
Mild cases often improve with rest and physiotherapy. Persistent pain that is left untreated can let the tendon worsen or tear, so ongoing symptoms are best assessed early.
Can I keep exercising or lifting weights with biceps tendonitis?
Gentle, guided movement usually helps, but avoid the activities that trigger the pain — heavy lifting and repetitive overhead work — until it settles. A physiotherapist can guide safe strengthening.
Do I need surgery for biceps tendonitis?
Most people never need surgery. It is considered only when several months of non-surgical treatment have not helped, or the tendon is significantly damaged.
What is the difference between biceps tendonitis and a rotator cuff problem?
They are different conditions but often related. The biceps tendon and rotator cuff sit close together in the shoulder, and one can irritate the other, which is why they are frequently assessed together.
When should I see a shoulder specialist?
If front-of-shoulder pain persists despite rest and physiotherapy, or you notice weakness or a bulge in the upper arm, it is worth seeing a shoulder specialist for assessment.
