Shoulder pain in a throwing athlete is not something I advise people to ignore. In my practice, I often see young athletes, club-level cricketers, badminton players, volleyball players, and even school or college students in Bangladesh who continue throwing or serving despite pain because they hope it will settle on its own. Sometimes it does improve with rest and correction of training errors, but in other cases the pain is a sign of a deeper shoulder problem that needs proper evaluation.
When I evaluate patients with this problem, one important point I want Bangladeshi patients to understand is that “throwing shoulder pain” is not a single disease. It is a symptom. The real cause may be tendon irritation, shoulder instability, labral injury, muscle imbalance, poor throwing mechanics, overuse, or in younger athletes, stress injury around the growth plate.
Why throwing causes shoulder pain
The shoulder is designed for a wide range of movement. That mobility is useful for throwing, but it also makes the joint more dependent on soft tissues for stability. During repeated overhead throwing, the rotator cuff muscles, labrum, capsule, and shoulder blade muscles all have to work together with the trunk and legs. If one part is overloaded or not functioning well, pain can develop.
In Bangladesh, I commonly see this in:
- cricketers, especially fast bowlers and fielders who throw hard
- badminton and tennis players
- volleyball players
- handball athletes
- gym-goers doing repeated overhead drills without proper form
- school-age athletes who increase training too quickly before tournaments
Common causes of shoulder pain in throwing athletes
Rotator cuff tendinitis or partial tear
The rotator cuff is a group of muscles and tendons that help stabilize and move the shoulder. Repetitive overhead activity can irritate these tendons. Athletes may feel pain at the front or side of the shoulder, especially during late cocking or follow-through.
Labral injury, including SLAP tear
The labrum is a ring of cartilage that helps deepen the socket of the shoulder. Throwing athletes can develop a labral injury from repeated stress. This may cause deep shoulder pain, clicking, catching, or loss of throwing power. Some athletes describe that the shoulder no longer feels “normal” during high-speed throwing.
Shoulder instability
Some athletes have a history of shoulder dislocation or subluxation. Others develop looseness over time from repetitive overhead activity. When the shoulder becomes unstable, the athlete may feel pain, weakness, or a sense that the shoulder is slipping during throwing.
Internal impingement
This is a problem often seen in overhead athletes when structures in the back of the shoulder get pinched during extreme throwing positions. Pain may occur mainly when the arm is cocked back.
Scapular dyskinesia
The shoulder blade plays a major role in safe overhead motion. If the muscles controlling the scapula are weak, tight, or poorly coordinated, the main shoulder joint may become overloaded. I often explain to patients that a painful shoulder is sometimes partly a “shoulder blade control” problem.
Little League shoulder or growth plate stress injury
In adolescents whose bones are still developing, repetitive throwing can irritate the growth plate near the upper arm bone. This is especially important in school athletes. Persistent pain in a teenage throwing athlete should never be dismissed as simple muscle soreness.
Symptoms that should not be ignored
When I evaluate patients with this problem, I ask exactly when the pain occurs and what the athlete feels during throwing. Important symptoms include:
- pain during throwing, especially at high speed
- pain after training that continues into the next day
- reduced throwing velocity or accuracy
- feeling of weakness or dead arm
- clicking, catching, or painful popping
- sense of instability or slipping
- loss of shoulder movement
- pain that spreads toward the upper arm
Urgent red flags
Some symptoms need quicker medical attention. Seek urgent evaluation if:
- the shoulder pain starts after a fall, collision, or sudden traumatic event
- the shoulder looks deformed or dislocated
- there is severe swelling, major weakness, or inability to lift the arm
- there is numbness, tingling, or significant pain going down the arm
- there is fever, redness, or unusual warmth around the joint
- a young athlete has persistent pain that continues despite rest from throwing
How I assess shoulder pain in a throwing athlete
I usually explain to my patients that the diagnosis depends on both history and examination. Imaging alone is not enough. A scan may show some changes, but the athlete’s symptoms, training pattern, and physical findings are what help us understand the real problem.
History
I ask about:
- the sport and playing position
- whether the athlete throws, bowls, serves, or smashes repeatedly
- when the pain began
- any recent increase in workload
- previous shoulder or elbow injuries
- whether there is loss of speed, endurance, or control
- whether pain occurs only during sport or also in daily life
Physical examination
I examine:
- shoulder movement
- rotator cuff strength
- signs of instability
- labral irritation tests
- scapular control
- neck and sometimes elbow, because pain patterns can overlap
