A sharp stab in your shoulder during a tennis serve at a local Henderson park, reaching for a tool on a high shelf, or even just lifting your arm to comb your hair, these moments stop you cold. Sharp shoulder pain is one of the most common reasons adults in our community seek orthopedic care, but not all sharp pain carries the same meaning.
At the Orthopaedic Institute of Henderson (OIH), our board-certified orthopedic surgeons have been diagnosing and treating complex shoulder conditions for more than 25 years. We often hear the same heartfelt question from our patients: Is this just tendonitis, or did I actually tear something?
Understanding the difference is vital because the treatment paths differ significantly, and an accurate diagnosis is the first step toward restoring your quality of life.
Tendonitis and Tears: What’s the Difference?
The shoulder is a complex ball-and-socket joint stabilized by muscles, tendons, and the labrum (a ring of cartilage). When sharp pain develops, it typically involves either inflammation of the tendons or structural damage to the joint itself.
Shoulder Tendonitis (Inflammation)
Tendonitis refers to the irritation of a tendon. In the shoulder, this most often affects the rotator cuff or the biceps tendon. It typically develops gradually from repetitive motions, common among swimmers, golfers, or professionals with repetitive lifting duties.
- The Feeling: Often starts as a dull ache but turns into a sharp “catch” when you reach behind your back or overhead.
- The Sign: The area may feel tender to the touch, and you might notice mild swelling.
Rotator Cuff and Labral Tears (Structural Damage)
A tear involves physical damage to the tissue. Rotator cuff tears can be partial (frayed) or full-thickness (detached from the bone). Labral tears involve the cartilage ring that stabilizes the socket.
- The Feeling: Tears often cause consistent sharp shoulder pain, significant weakness, and “mechanical” symptoms like catching, grinding, or popping.
- The Sign: Unlike tendonitis, tears frequently cause pain that persists even at rest and makes the arm feel “heavy” or weak.
Signs to Help You Tell the Difference
While both conditions cause significant discomfort, their symptoms often diverge in subtle ways.
- Symptoms of Tendonitis: The pain usually feels “surface-level” and is often accompanied by localized heat or tenderness. It tends to flare up during activity but may settle down once you have rested the arm for a few days.
- Symptoms of a Tear: This pain is often deep and persistent. One of the biggest indicators of a tear is night pain; if you find it impossible to sleep on your side or if the ache wakes you up throughout the night, it is a strong signal that the tissue is torn. Additionally, tears often cause a “mechanical” sensation, where the joint feels like it is catching or locking in place.
Why a Professional “Root-Cause” Diagnosis Matters
Self-diagnosing shoulder pain is risky. Left untreated, tendonitis can progress into a tear, and what feels like a minor strain could be a partial tear that worsens with every game of golf or work shift.
At OIH, our diagnostic approach focuses on the root cause:
- Comprehensive History: We listen to your story, when the pain started and how it affects your daily joy.
- Physical Exam: We test your range of motion and strength to isolate the specific structure involved.
- Advanced On-Site Imaging: OIH offers on-site X-rays and MRI to visualize soft tissues like the rotator cuff and labrum. This ensures we aren’t guessing at your diagnosis but seeing the exact nature of the injury.
OIH’s Treatment Philosophy: Conservative Care First
We believe in exploring every non-surgical option to reduce the need for surgery whenever possible. Your personalized plan may include:
- Physical Therapy: Specialized programs to strengthen the “scapular stabilizers” and restore normal movement.
- PRP and Corticosteroid Injections: Using advanced medicine to reduce inflammation and promote natural healing within the tendon.
- Activity Modification: Practical guidance on how to stay active while protecting your joint.
Advanced Surgical Excellence
When a tear is complete or conservative care isn’t enough, our surgeons specialize in minimally invasive arthroscopic surgery.
- Arthroscopic Rotator Cuff Repair: Reattaching the tendon using small anchors through tiny incisions, leading to less pain and faster recovery.
- Labral Repair: Restoring stability to the shoulder socket to eliminate “locking” sensations.

FAQs
It is serious if you experience significant arm weakness, a “popping” sound during injury, or pain that consistently prevents sleep and daily movement.
No, many patients find lasting relief through conservative treatments like physical therapy and injections without ever requiring a surgical procedure.
Tendonitis is the inflammation of the tendons themselves, while bursitis involves the swelling of the small, fluid-filled sacs that cushion the shoulder joint.
While light movement begins within weeks, a full return to sports or heavy lifting typically requires four to six months of dedicated rehabilitation.
Lying down changes the alignment of the joint and increases pressure on inflamed tissues, often leading to sharp pain when rolling onto the affected side.
