Key Points about Shoulder Impingement Syndrome
- When the shoulder bones cause impingement of the tendons or bursa in the shoulder, impingement syndrome may occur.
- The most common syndrome of shoulder impingement syndrome is persistent shoulder pain that makes overhead activities difficult.
- People who perform activities that require repetitive overhead movements such as swimming, tennis, lifting, and painting are at higher risk for developing shoulder impingement syndrome.
Shoulder impingement syndrome, also known as impingement syndrome, occurs when the bones of the shoulder impinge on the tendons or bursa in that area.
Impingement syndrome causes persistent pain and can cause disrupt you from performing your everyday activities, like reaching up overhead, putting on a coat, or reaching up behind the back can cause pain.
If left untreated, impingement syndrome can lead to inflammation of tendons (tendinitis) and/or bursa (bursitis). If not treated correctly, the rotator cuff tendons will begin to thin and tear.
Shoulder impingement syndrome causes
Most of the time, impingement syndrome is caused by overuse. Using your shoulder repeatedly can cause the tendons to swell and ‘catch’ on the upper shoulder bone.
In other cases, the cause is unknown.
Shoulder impingement syndrome symptoms
The primary symptom of shoulder impingement syndrome is a sudden pain in the shoulder when you lift your arms above your head.
Other symptoms of shoulder impingement syndrome include:
- Shoulder and arm weakness
- Worse pain at night
- Minor and constant pain in the arm
- Pain from the front of the shoulder to the side of the arm
Shoulder impingement syndrome complications
When not diagnosed and treated immediately, shoulder impingement can lead to rotator cuff degeneration and potentially a tear.
Other complications associated with shoulder impingement include:
- Frozen shoulder
- Rotator cuff tear
- Long-term pain in the shoulder or arm
Shoulder impingement syndrome risk factors
Impingement syndrome is most common in young athletes and middle-aged people. People who participate in sports or jobs that require an individual to perform repetitive overhead activity are at a higher risk of developing it.
These jobs and sports may include:
- Baseball, tennis, and swimming
- Painters, carpenters or electricians
Shoulder impingement syndrome prevention
- Train smart: If you are exercising, don’t do too much too fast. Ramp up your training at a reasonable rate.
- Balance your muscles: Try not to focus on exercising one muscle and balance your workouts. Impingement can happen from overusing the muscles in the shoulders.
- Posture: Poor posture can cause shoulder impingement.
- Keeping inflammation under control: After working out, exercising, or working intensely, apply ice on your shoulder for about 20 min.
- Move correctly: If you are playing sports, be sure you are moving correctly and have someone analyze your movements.

- Physical therapy – Physical therapy can help strengthen the muscles in the shoulder.
- Medications – Nonsteroidal anti-inflammatory medications such as Advil can relieve pain and swelling

Most cases will heal in three to six months, but more severe cases can take up to a year to heal.
