Many people with a torn biceps tendon at the shoulder do not need surgery. This tear is usually of the long head of the biceps, which runs over the front of the shoulder into the joint. It often causes a bulge low in the upper arm, sometimes called a Popeye arm. Pain and bruising usually settle over 4 to 8 weeks. Strength loss is often small, mostly in turning the palm up. Surgery is mainly considered for some younger, active people or heavy manual workers.
A tear at the other end of the biceps, at the elbow, is different. It causes more weakness, and repair is time-sensitive, usually within the first few weeks. If the pop and pain were at the front of the elbow, see a doctor promptly.
This page assumes you have been checked by a doctor. The long head tendon often tears after years of wear, so it is more common after about 40, and often happens alongside rotator cuff problems.
Key takeaways
- Often managed without surgery: many long head biceps ruptures at the shoulder are treated with rest, pain relief and exercise.
- The Popeye bulge: the muscle bunches lower in the upper arm. It is usually permanent without surgery and rarely affects function.
- Strength loss: often small, mainly in turning the palm up, and less in bending the elbow.
- Typical course: pain and bruising usually settle over 4 to 8 weeks; strength keeps building for about 3 months.
- Elbow-end tears differ: a biceps tear at the elbow has a time-sensitive repair window and needs prompt assessment.
Where are you right now?
- It has just happened: start with “Do you need surgery?” and the week-by-week section.
- Weeks in and not settling: go to “If it isn’t going to plan”. Ongoing shoulder pain often comes from the rotator cuff.
- After an injection or surgery: after a biceps reattachment (tenodesis), your surgeon’s protocol comes first.
- Getting back to work or sport: the “When can I…” table gives typical ranges.
Do you need surgery?
The biceps has two tendons at the shoulder. When the long head tears, the short head still anchors the muscle, and the arm keeps most of its strength. That is why many people choose not to have it reattached.
Surgery to reattach the tendon (biceps tenodesis) is more often discussed when:
- Work or sport needs it: heavy manual work or sport that relies on turning the forearm with force.
- Cramping persists: the muscle keeps cramping or aching with use after the first few months.
- Appearance matters to you: some people want to avoid a lasting bulge.
- Other surgery is planned: for example, a rotator cuff repair, where the biceps can be dealt with at the same time.
If you are considering reattachment, ask about timing early. Repair is usually easier within the first few weeks, before the tendon pulls back and shortens.
Week by week
- Days 1 to 7: pain at the front of the shoulder and upper arm, with bruising that may spread toward the elbow. Ice for 15 to 20 minutes at a time and avoid heavy lifting. A sling is rarely needed beyond a few days.
- Weeks 1 to 4: pain eases. Gentle elbow and shoulder movement keeps the joints from stiffening. Light daily tasks are usually fine.
- Weeks 4 to 8: bruising fades. Strengthening for the biceps, forearm and shoulder builds gradually.
- Months 2 to 3: most people return to normal activity. Some notice muscle cramping or fatigue with heavy or repeated use, which often eases over months.
The bulge changes how the arm looks more than how it works.
Where else this could be coming from
- Biceps tendon irritation (biceps tendinopathy): pain in the same groove at the front of the shoulder, but no pop and no bulge.
- Rotator cuff tear: often present alongside a biceps rupture. Weakness lifting the arm out to the side or turning it out points here.
- SLAP tear (labral tear at the top of the socket): deep catching or clicking where the biceps attaches, usually in younger, active people.
- Pectoralis major tear: a pop at the front of the chest and armpit during a heavy push, such as a bench press, with bruising across the chest.
- The neck: arm pain with tingling, or pain that changes with neck movement.
Is this normal?
- “The pain eased right after the pop.” Common. If the tendon had been painful for months, the rupture can bring relief.
- “The bruise has spread down past my elbow.” Common in the first 1 to 2 weeks as the bruise moves down with gravity.
- “My arm cramps when I use a screwdriver.” Cramping with repeated forearm turning is common in the first months and often settles.
- “The bulge has not gone.” Expected. Without surgery the muscle sits lower for good.
If it isn’t going to plan
It is week six. The bulge no longer bothers you, but lifting the laundry basket onto the dryer still sends an ache through the front of the shoulder. The thought in your head is that the biceps is torn, so this is just how the arm will be now.
A long head rupture alone usually stops hurting within weeks. Pain that lingers at the shoulder is often coming from something else, most often the rotator cuff, which commonly wears alongside the biceps tendon. Weak shoulder muscles also leave the joint less supported for lifting.
What the shoulder usually needs is a check of the rotator cuff and graded strengthening of the cuff, the shoulder blade muscles and the remaining biceps.
If you are 6 weeks in and the shoulder still hurts with lifting, get assessed by a physical therapist or your doctor. Ask:
- Rotator cuff: could the rotator cuff also be involved, and would a scan help?
- Exercise: which strengthening exercises suit me now, and how should they progress?
- Surgery: given my work, is reattachment worth discussing, and is it still an option?
When can I…
| Activity | Typical range |
|---|---|
| Sleep on that side | Often 2 to 6 weeks after a long head biceps rupture without surgery |
| Drive | Often within 1 to 2 weeks, once you can steer comfortably |
| Reach overhead | Often 2 to 6 weeks |
| Lift | Light loads within 2 to 4 weeks; heavier lifting often 6 to 12 weeks |
| Desk work | Often within days |
| Manual work or sport | Often 6 to 12 weeks; longer after reattachment surgery |
If you have had surgery, your surgeon’s protocol comes first.
Call your local emergency number or go to the emergency department if
- Tight, swelling arm: the upper arm or forearm swells fast, feels tight and hard, and pain is severe and rising.
- Circulation: the hand turns cold, pale or blue.
- Chest symptoms: left arm or shoulder pain comes with chest pressure, breathlessness or sweating.
See a doctor today if
- Pop at the elbow: the pop, pain or bruising is at the front of the elbow, or the bulge sits higher in the arm.
- Not yet checked: you felt a pop with a new bulge and no one has examined it.
- Numbness: new numbness, tingling or weakness in the forearm or hand.
Get it checked soon if
- Weak lifting: you struggle to lift the arm out to the side or overhead.
- Lingering pain: shoulder pain is not clearly easing after 6 weeks.
- Thinking about surgery: you want to discuss reattachment while it is still straightforward.

A torn biceps at the shoulder usually leaves a working arm, and the decision about surgery is often yours to weigh.
