Shoulder
Biceps Tendinopathy
Biceps tendinopathy is pain at the front of the shoulder from the long biceps tendon, aggravated by lifting, curling and overhead work. Common in gym-goers and over-40s.
Common symptoms
- Sharp or aching pain at the front of the shoulder
- Pain spreading down the front of the upper arm
- Pain with bicep curls, pull-ups and lifting bags
- Tenderness when pressing the groove at the front of the shoulder
- Pain reaching overhead or behind you
- Occasional clicking or snapping at the front of the shoulder
- Night ache after a heavy training day
Overview
The biceps muscle in your upper arm has two tendons at the shoulder end. The "long head" tendon runs up through a groove at the front of the upper arm bone and into the shoulder joint itself, where it attaches to the top of the socket. This tendon is the one that usually becomes painful.
Biceps tendinopathy is an overuse condition: the tendon becomes irritated, thickened and sore, typically from repeated lifting, pulling or overhead activity. It produces a sharp or aching pain at the front of the shoulder that may travel down the front of the upper arm, and is felt when curling, lifting a bag, reaching overhead, or pushing up from a chair.
It rarely occurs in isolation. Because the tendon runs through the shoulder joint, it is often irritated alongside rotator cuff tendinopathy or impingement, and in people over 40 it may be associated with a worn labrum. Occasionally the tendon can rupture — producing a sudden "pop" and a bulge in the upper arm (a "Popeye" sign) — which, perhaps surprisingly, often hurts less afterwards.
Causes and risk factors
- Repetitive lifting, pulling or curling in the gym, especially sudden increases in volume
- Overhead sport: swimming, throwing, racket sports, climbing
- Manual work involving repeated lifting
- Age over 40, as the tendon becomes less tolerant of load
- Coexisting rotator cuff tendinopathy or impingement
- Poor shoulder blade control and a rounded posture that compresses the front of the shoulder
How we may be able to help
We begin by assessing the whole shoulder, since biceps pain often travels with rotator cuff and shoulder blade problems. Specific tests load the biceps tendon and help confirm it as a source of pain. If we suspect a significant tear, a labral injury or a rupture, we can arrange an online GP consultation for an ultrasound scan or MRI and a specialist opinion.
Physiotherapy centres on a graded loading programme for the tendon — starting with isometric holds to settle pain, then controlled curls and shoulder work that progressively rebuild its capacity — alongside correcting the shoulder blade and cuff issues that overload it. We combine this with hands-on treatment: IASTM along the tendon and the tight biceps muscle belly, dry needling for the tight upper arm muscles and cupping for the chest muscles that pull the shoulder forward, and kinesiology taping to offload the tendon in the early stage.
For stubborn, long-standing tendinopathy, focused shockwave therapy may help stimulate the tendon's recovery. Therapeutic ultrasound can be used over the groove at the front of the shoulder for pain relief while loading begins. Our chiropractor can treat upper back stiffness that keeps the shoulder in a cramped, forward position.
What you can do at home
- Reduce the volume of curls, pull-ups and overhead pressing for now rather than stopping all training
- Try a gentle isometric hold: elbow bent to 90 degrees, press your palm up against a table edge for 30–45 seconds
- Carry shopping with the elbow straight and the bag close to your body
- Stretch your chest and sit taller to take pressure off the front of the shoulder
- Ice the front of the shoulder for 10–15 minutes after aggravating activity if it helps
- Avoid sudden jerky lifts, which tendons tolerate poorly
When to seek urgent help
If you have any of the following, call us straight away for an urgent same-day appointment — we can examine you and arrange fast-track X-ray or MRI through our imaging partner. If you cannot reach us, go to A&E. For loss of bladder or bowel control, numbness around the groin, chest pain, a sudden severe headache or rapidly worsening weakness, call 999 or go to A&E immediately:
- A sudden 'pop' at the shoulder followed by a new bulge in the upper arm — possible tendon rupture; seek assessment promptly
- A hot, red, swollen shoulder with fever
- Shoulder or arm pain with chest pain, breathlessness or sweating
- Marked weakness bending the elbow or turning the palm up after an injury
Frequently asked questions
Is it my biceps or my rotator cuff?
Often both are involved, as the long biceps tendon runs through the same crowded space. Our assessment tests each separately, and the treatment plan addresses whichever structures are contributing.
Should I get a scan?
Usually not at first. If there has been a sudden pop, a visible change in the arm shape, or you are not improving with a good loading programme, we can arrange an ultrasound scan or MRI through our online GP service.
Can I keep doing curls?
Usually yes, at reduced load and with slower, controlled movements. Tendons generally respond better to modified loading than to complete rest. Your therapist will set a starting point.
What if the tendon ruptures?
A long-head rupture is often managed without surgery, especially in older adults, as the other tendon takes over most of the work. The cosmetic bulge usually remains. A specialist opinion is advised in younger, active people.
