Shoulder Impingement Treatment in NJ & NY
Every overhead reach catches halfway up as if something inside your shoulder is pinching shut. Stacking a box on a high shelf, washing your hair, or changing a ceiling light bulb sends a sharp pain through the top of your shoulder that forces your arm back down. Metro Pain Centers identifies the structure being compressed beneath your acromion and treats it so you can reach overhead without the catch stopping your arm mid-arc.
Understanding Shoulder Impingement at Metro Pain Centers
Shoulder impingement is the compression of the rotator cuff tendons and subacromial bursa between the humeral head and the coracoacromial arch during arm elevation, producing pain, weakness, and functional limitation as the soft tissue structures are repeatedly pinched within the narrowed subacromial space every time the arm rises above shoulder height.
Coracoacromial arch narrowing, the reduction of the subacromial space caused by acromial spurring, thickened coracoacromial ligament, acromioclavicular joint osteophytes, or swollen rotator cuff tendons that progressively decrease the clearance between the acromion above and the humeral head below, is the structural mechanism Metro Pain Centers evaluates to determine which component of the arch is contributing to the impingement and to select the targeted treatment that restores adequate subacromial clearance.
External impingement from the coracoacromial arch accounts for approximately 65 percent of all shoulder pain evaluated in primary care settings. It is the most common diagnosis among patients presenting with painful overhead arm use.
Metro Pain Centers treats subacromial impingement, internal impingement, coracoid impingement, and secondary impingement from glenohumeral instability. Our physicians distinguish between these types because each involves a different structure compressing the rotator cuff.
Understanding Your Condition
Our board-certified physicians use advanced diagnostic techniques to accurately identify the source of your pain, ensuring you receive the most effective treatment.
Symptoms of Shoulder Impingement
Pain during the mid-arc of arm elevation between 60 and 120 degrees, called the painful arc, is the signature finding. The arm passes through this zone with a sharp catch before the pain eases above 120 degrees. Metro Pain Centers uses the painful arc boundaries to localize the impingement within the subacromial space.
Difficulty reaching behind the back to tuck in a shirt or fasten a bra suggests impingement during combined extension and internal rotation. The acromion compresses the rotator cuff in this combined position. Our pain management physicians test this motion to assess the severity of impingement.
Weakness when raising the arm against resistance indicates the rotator cuff tendon is being compromised by the ongoing compression. Metro Pain Centers measures supraspinatus strength to determine whether the impingement has progressed to tendon damage.
An aching sensation that spreads from the shoulder down the lateral arm to the elbow after overhead activity suggests ongoing bursal and tendon inflammation. Our specialists track pain radiation patterns to monitor whether the impingement is worsening.
What Causes Shoulder Impingement
Acromial spurring narrows the subacromial space from above. Bone spurs on the undersurface of the acromion or the acromioclavicular joint press into the rotator cuff during arm elevation. Metro Pain Centers identifies acromial spurs on X-ray and uses this information to explain why the impingement developed.
Rotator cuff weakness allows the humeral head to migrate superiorly during arm elevation, reducing the space from below. When the supraspinatus and infraspinatus cannot hold the humeral head centered in the glenoid, it rises and compresses the tendon against the acromion. Our physicians evaluate cuff strength because weakness-driven impingement responds to rehabilitation differently than spur-driven impingement.
Scapular dyskinesis alters the position of the acromion relative to the humeral head during arm movement. Poor scapular mechanics tilt the acromion downward and reduce subacromial clearance. Metro Pain Centers assesses scapular motion patterns to identify this often-overlooked contributor.
Repetitive overhead sports and occupations place sustained demand on the subacromial space. Swimming, throwing, painting, and overhead construction work produce thousands of impingement-loading cycles per week. Our physicians assess activity history to identify and modify the mechanical triggers.
How Metro Pain Centers Diagnoses Shoulder Impingement
Physical examination includes the Neer impingement sign, Hawkins-Kennedy test, painful arc assessment, empty can test for supraspinatus function, and scapular dyskinesis evaluation. Our board-certified pain specialists use these findings to confirm impingement and identify which structure within the subacromial space is being compressed.
X-rays reveal acromial morphology, acromial spurs, acromioclavicular joint hypertrophy, and calcific tendinitis. Metro Pain Centers orders outlet view and AP views to visualize the subacromial space and the bony structures that narrow it.
Ultrasound provides real-time dynamic assessment of the rotator cuff tendons gliding beneath the acromion during arm elevation. Our physicians use ultrasound to watch the impingement occur in real time and to detect partial rotator cuff tears caused by the compression.
Diagnostic subacromial injection with local anesthetic, known as the Neer impingement test, confirms the subacromial space as the pain source. When the injection eliminates the painful arc temporarily, Metro Pain Centers uses that positive result to confirm the diagnosis and plan targeted treatment.
Treatment Options for Shoulder Impingement at Metro Pain Centers
Ultrasound-guided subacromial injections deliver corticosteroid into the inflamed space beneath the acromion to reduce bursal swelling and rotator cuff inflammation. Metro Pain Centers uses image guidance to ensure the medication reaches the exact tissue interface where the impingement occurs.
Acromioclavicular joint injections target impingement driven by AC joint osteophytes. Our physicians inject the AC joint under ultrasound guidance when examination and imaging confirm that the AC joint is contributing to subacromial space narrowing.
Interventional pain management at Metro Pain Centers includes suprascapular nerve blocks for patients with chronic impingement-related shoulder pain who need sustained relief while rehabilitation restores rotator cuff and scapular function.
Physical therapy is the cornerstone of impingement treatment, focusing on rotator cuff strengthening, scapular stabilization, posterior capsule stretching, and movement retraining. PRP therapy supports tendon healing in patients whose rotator cuff has developed tendinopathy or partial tears from prolonged impingement.

Related Conditions Treated by Metro Pain Centers
Shoulder impingement frequently coexists with other conditions our physicians treat. Shoulder pain is the broad symptom category, and confirming impingement as the specific mechanism directs treatment to the correct structural cause.
Rotator cuff injury develops when prolonged impingement damages the tendon. Shoulder bursitis is the inflammatory response of the subacromial bursa to impingement compression. Shoulder tears result when impingement progresses beyond tendinopathy to tissue failure.

Why does my shoulder catch when I reach overhead?
The rotator cuff tendons and subacromial bursa are being pinched between the humeral head and the acromion as your arm rises. Metro Pain Centers identifies which structure within the subacromial space is catching and treats it directly.
Will shoulder impingement get worse without treatment?
Untreated impingement progressively damages the rotator cuff tendon through repetitive compression. A tendinopathy can advance to a partial tear and then a full-thickness tear. Metro Pain Centers treats impingement early to prevent this progression.
Can I still work out with shoulder impingement?
Exercises below shoulder height are generally safe. Overhead pressing, lateral raises above 90 degrees, and behind-the-neck movements should be avoided until treatment restores subacromial clearance. Metro Pain Centers modifies your program accordingly.
What is the difference between impingement and a rotator cuff tear?
Impingement is the compression mechanism. A rotator cuff tear is the tissue damage that impingement can produce. Metro Pain Centers uses ultrasound to determine whether the impingement has already caused a tear.
