Shoulder Impingement

Pinched rotator cuff tendons in the shoulder

Shoulder impingement is irritation of the rotator cuff tendons as they pass under the bony acromion, often producing pain with overhead activity. Same-day or next-week evaluations across eight LA-area offices.

Common shoulder & elbow concerns we treat

  • Pain that limits walking, lifting, or sleep

  • Board-certified specialists, not generalists

Key takeaways

  • Shoulder impingement is one of many shoulder & elbow conditions our specialists evaluate every day.
  • Most patients improve with conservative care: rest from overhead activity, physical therapy, anti-inflammatory medication, and a steroid injection when needed.
  • When a procedure is the right call, we explain every option, recovery timeline, and return-to-activity milestone.
  • On-site imaging at most offices and same-day appointments across eight Los Angeles-area locations.

What is shoulder impingement?

Shoulder impingement is irritation of the rotator cuff tendons as they pass under the bony acromion, often producing pain with overhead activity. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.

Most patients with shoulder impingement improve with conservative care: rest from overhead activity, anti-inflammatory medication, physical therapy to strengthen the rotator cuff and shoulder blade muscles, and a steroid injection when pain is limiting progress. Surgery is considered only when symptoms persist after several months of this care.

Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose shoulder impingement, and the full range of treatment options, from the simplest to the most involved.

Watch: Shoulder Impingement Syndrome

This is a painful pinching of soft tissues in your shoulder. It happens when these tissues rub and press against a part of your shoulder blade called the "acromion." This can irritate your rotator cuff tendons, and also a soft sac called the "subacromial bursa."

Inside the shoulder & elbow.

The shoulder is the most mobile joint in the body, which makes it vulnerable to instability and impingement. The elbow is a hinge that lets you reach, lift, and rotate the forearm. Both rely on tendons and ligaments that can tear or fray over time.

Symptoms and causes of shoulder impingement

Common symptoms

  • Pain reaching overhead or behind the back
  • Pain on the outside or front of the shoulder
  • Weakness lifting the arm
  • Pain at night, especially lying on the affected side

Common causes

  • Repetitive overhead use (swimming, painting, throwing)
  • Bone spur on the acromion
  • Rotator cuff weakness or muscle imbalance
  • Poor posture or scapular dyskinesis

How we diagnose shoulder impingement

You want answers, fast, and we're built to give them. Most patients leave their first LAOSS visit with a clear diagnosis and a written plan, not another referral chain.

Here's what your initial visit for shoulder impingement typically looks like:

  • Detailed history: when it started, what makes it better or worse, what you've already tried
  • Focused exam of the shoulder & elbow: range of motion, stability, strength, specific provocation tests
  • On-site imaging at most offices: X-ray for bone, ultrasound or MRI when soft-tissue detail is needed
  • A written plan with options ranging from conservative care to surgical procedures, in plain English

Schedule your evaluation at the LAOSS office nearest you.

How we treat shoulder impingement at LAOSS

Once we've confirmed the diagnosis, the next step is matching the right treatment to your situation. We start with the least-invasive option that fits, and escalate only when it doesn't.

Conservative care
Step 1

Conservative care first

Non-surgical options designed to relieve pain, restore movement, and avoid the OR when possible.

  • Rest from overhead and other painful activities
  • Anti-inflammatory medication and ice
  • Physical therapy for rotator cuff and shoulder blade strength
  • Stretching and posture work for a tight shoulder
  • Steroid injection into the space above the rotator cuff (subacromial injection)
Surgical care
When needed

Surgical options when needed

Surgery is considered only when several months of therapy and injections have not relieved the pain.

  • Arthroscopic subacromial decompression, which removes inflamed bursa and creates more room for the rotator cuff
  • Smoothing of a bone spur on the acromion (acromioplasty)
  • Rotator cuff repair if a tear is found
  • Physical therapy after surgery to restore motion and strength

Why experience matters.

Why experience matters

Shoulder & elbow care is highly technique-dependent. Volume, training, and judgment together determine the outcome you actually feel six months later.

  • Precise diagnosis from imaging and exam
  • Conservative-first care that avoids unnecessary surgery
  • Surgical technique refined over thousands of cases
  • On-site imaging + coordinated PT through your in-network provider

The LAOSS approach

Our shoulder & elbow specialists move stepwise: start with the least-invasive option that fits your situation, escalate only when it doesn't.

  • Same-day imaging at most offices
  • PT coordinated in your insurance network
  • Board-certified surgeons performing the procedures themselves
  • Direct access to your specialist between visits

Am I a candidate?

If most of these match your situation, an evaluation with a shoulder & elbow specialist is the next step.

You may be

You may be a candidate if

These signs typically point toward an in-person evaluation with a shoulder & elbow specialist.

  • Pain or stiffness in the shoulder & elbow that lasts more than a few days
  • Swelling, instability, or noticeable change in function
  • Symptoms that limit walking, lifting, sleep, or work
  • Previous treatment that didn't fully resolve the problem
  • Imaging or exam findings that suggest an underlying issue
Evaluation

What evaluation includes

Your first visit is built to give you an answer the same day, not just another referral.

  • Detailed history: onset, mechanism, what makes it better or worse
  • Hands-on exam focused on the affected joint or region
  • On-site imaging at most offices (X-ray, ultrasound)
  • Clear plan with options ranging from conservative to surgical
  • Same-day or next-day scheduling for any follow-up tests

ImportantSeek urgent evaluation for sudden severe pain, numbness, progressive weakness, or any sign of infection (fever, increasing redness or swelling).

Your shoulder & elbow recovery roadmap.

Recovery is rarely a straight line, but a clear plan with measurable milestones makes the path predictable.

  1. Days 0 to 14

    Right after care

    In the first two weeks we focus on protecting the shoulder & elbow, calming inflammation, and restoring basic motion.

    • Activity modification with clear do/don't guidance
    • Ice and pain control as needed
    • Gentle range-of-motion within safe limits
    • Follow-up scheduled to track healing
  2. Weeks 2 to 8

    Rehabilitation

    Targeted physical therapy rebuilds strength, mobility, and confidence in the shoulder & elbow.

    • Progressive strengthening and neuromuscular work
    • Manual therapy and soft-tissue treatment
    • Sport- or job-specific movement re-training
    • Coordinated PT through your in-network provider
  3. Months 2+

    Long-term care

    Once function is restored, the focus shifts to keeping you there, and catching any recurrence early.

    • Return-to-activity plan with measured benchmarks
    • Home program tailored to your sport or job
    • Maintenance visits or imaging if symptoms change
    • Direct line back to your specialist if needed
Risks & considerations

What to weigh before you decide.

We talk through the risks and benefits with every patient. Informed consent is a conversation, not a form.

General

General considerations

Every orthopedic intervention carries a small set of standard risks. We screen, prepare, and monitor for these on every patient.

  • Infection (rare with modern technique and prophylaxis)
  • Bleeding or bruising at the treatment site
  • Reaction to anesthesia or medications
  • Need for additional procedures in some cases
Specific

Shoulder and elbow considerations

Some risks are tied to the structures we're treating in the shoulder & elbow. We discuss these in detail at your visit so you can weigh them against the benefits.

  • Temporary stiffness or weakness during recovery
  • Incomplete pain relief in a small percentage of cases
  • Nerve or vessel irritation near the treatment area
  • Need for follow-up therapy to fully restore function
