Tendonitis of the long head of the biceps

Tendonitis of the long head of the biceps is an inflammatory condition affecting the upper biceps tendon, causing pain at the front of the shoulder, localised tenderness, and reduced overhead function.

What causes biceps tendonitis?

Biceps tendonitis is primarily driven by chronic wear and tear or repetitive overhead loading: Repetitive microtrauma and overuse: Repeated overhead arm actions cause the tendon to continuously slide back and forth within the bicipital groove, leading to chronic friction and inflammation. This is particularly prevalent in athletes involved in swimming, tennis, golf, throwing sports, and weightlifting. Age-related wear: Over time, natural wear frays the tendon fibers, reducing their structural elasticity and loading capacity. Traumatic injury: Sudden direct force, lifting an excessively heavy load, or falling onto an outstretched arm.

Primary symptoms

  • Pain and localised tenderness at the front of the shoulder, which may radiate down the upper arm bone
  • Pain that worsens during overhead reaching, throwing, pulling, or lifting movements
  • An aching sensation in the biceps muscle at rest or following physical activity
  • An audible or physical clicking, snapping, or popping sensation at the front of the shoulder during movement

 

How is biceps tendonitis diagnosed?

Diagnosing tendonitis of the long head of the biceps involves a thorough physical evaluation by your consultant to isolate the source of anterior shoulder pain and check for associated joint pathologies.

How is it treated?

Treatment focuses on calming localised inflammation, restoring painless overhead mobility, and managing any co-existing shoulder conditions.

Treatment routes for biceps tendonitis

The majority of biceps tendonitis cases resolve without surgery. Initial management includes resting from aggravating overhead activities, applying ice packs (wrapped in a damp towel) for 15–20 minutes several times daily, and taking non-steroidal anti-inflammatory medications (NSAIDs) under medical direction. A tailored physical therapy program focuses on restoring full range of movement and strengthening the rotator cuff and scapular stabilizing muscles. Target ultrasound-guided corticosteroid injections into the biceps tendon sheath may also be offered to rapidly reduce severe pain and inflammation.

Recovery from biceps tendonitis

0–2 weeks

Initial protection and light function

Following surgery, a protective sling is worn for comfort. Most individuals can perform light desk-based activities (such as typing or writing) immediately. Focus on keeping surgical dressings clean and dry, alongside gentle hand, wrist, and finger movements. Stitches are checked or removed around 10 to 14 days post-operation.

2–6 weeks

Passive and active mobility

Under physical therapy guidance, sling use is phased out. Progressive passive and active-assisted movement exercises begin, ensuring range of motion is restored without placing heavy active resistance on the biceps tendon.

6–12 weeks

Active strengthening

Active biceps loading and rotator cuff strengthening exercises are gradually introduced. Pain levels improve significantly, allowing a return to routine daily activities and light physical exertion.

3–6 months

Full functional recovery and sports clearance

Rehabilitation progresses to advanced overhead conditioning, heavy resistance training, and sport-specific drills. Return to competitive overhead sports (such as tennis or swimming) or heavy manual labor typically occurs between 3 and 5 months post-surgery.
