Why Does My Shoulder Hurt When I Reach Across My Body?
Shoulder impingement and rotator cuff injuries are among the most common causes of shoulder pain (1). Both can cause shoulder pain when reaching across the body.
Shoulder impingement is a painful condition in which the bursa and muscles of the shoulder are pinched or compressed. This occurs in any area called the subacromial space which is immediately beneath the AC joint. This area contains the rotator cuff tendons and bursae and is identified by the red in the illustration below (2). A bursa is a fluid-filled sac that reduces the friction on tendons and muscles as they cross boney surfaces. A tendon is a thick collagen tissue that connects muscles to bones. The rotator cuff tendons provide important support and enable movement in the shoulder.
Rotator Cuff Injuries
There are four rotator cuff tendons: supraspinatus, infraspinatus, subscapularis, and teres minor. Injuries can include inflammation of the tendon called tendonitis and tears in the tendon. Tears can be partial thickness where they only involve a portion of the tendon or full-thickness when they involve the entire tendon. If the tendon fibers pull apart from one another this is called a retraction. Rotator cuff tears are common and the incidence increases with age. A recent large study demonstrated a prevalence of rotator cuff abnormalities of 9.7% in patients younger than 20 which increased to 62% in patients aged 80 and older (3). Factors that increase your risk for RC tears include advancing age, hand dominance (4), and smoking (5). Learn more about our non-surgical rotator cuff tear treatment.
What Does Shoulder Impingement Feel Like?
Pain is the most common symptom. It typically occurs with the elevation of the arm, forced movement overhead, and when lying on the shoulder. Impingement can also cause shoulder pain when reaching across the body.
Arm Pain at Night
Arm pain at night can be miserable. The pain can interrupt your sleep and erode your quality of life. Irritability becomes increasingly more common. What are the causes? When should I worry about it? What are the treatment options for arm pain at night? The neck is composed of 7 boney building blocks numbered 1- 7. Sandwiched between the bones is a disc that functions as an important shock absorber. The cervical discs are susceptible to injury due to trauma, degeneration, repetitive motion, and surgery. Common disc injuries include disc bulges, and herniations. The injured disc can compress or irritate one or more nerves resulting in arm pain at night. It can…
Learn to know the symptoms and causes of shoulder blade pain as well as the diagnostic tests to run for it and its treatment options. Shoulder blade pain can be a common, annoying, hard to diagnose problem. There are many different causes of shoulder blade pain and the exact cause of the shoulder blade pain will determine what type of treatments would be recommended.
A muscle spasm, also known as a muscle cramp, is a sudden and involuntary contraction or tightening of a muscle or group of muscles. This can occur in any part of the body but is most commonly experienced in the legs, arms, and back. These spasms can last for a few seconds up to many minutes. Occasional muscle spasms may not be something to worry about, but chronic muscle spasms can be a serious issue. In the shoulder, there are many muscles that can go into spasm. These spasms or cramps can cause pain, stiffness, and limited mobility.
The Scapula is your shoulder blade. It is a large triangular bone that compromises part of the shoulder joint. The Scapula is positioned over the back chest wall and ribs where it moves in different directions with shoulder movements (1). The Scapula meets with the arm bone (humerus) to form the shoulder joint. It also meets with the clavicle to form the AC joint. Multiple structures attach onto the Scapula which provides important support and movement for the scapulae and shoulder joint (2). These include:- Muscles/Tendons: Multiple muscles attach to the Scapula which include the deltoid, supraspinatus, infraspinatus, triceps, and teres minor.
Shoulder joint pain is the third most common reason that people see their primary care physician (1). It is commonly experienced by people who use their hands overhead a lot, particularly in occupations such as painting and construction.
Individuals who train with repetitive overhead movements, such as tennis players, swimmers, and basketball players, are also prone to develop shoulder joint pain.
The symptoms and progression of pain in the shoulder joint can vary from person to person, depending on what is causing it. We’ll discuss the causes of shoulder pain, how it is diagnosed, and how it is treated.

What causes shoulder pain when reaching across the body? What is shoulder impingement? What does shoulder impingement feel like? Can a shoulder X-ray show shoulder impingement? What are the treatment options for shoulder pain when reaching across the body? ulder impingement and rotator cuff injuries are among the most common causes of shoulder pain (1). Both can cause shoulder pain when reaching across the body. Shoulder impingement is a painful condition in which the bursa and muscles of the shoulder are pinched or compressed.
There are several reasons why shoulder pain at night occurs or is aggravated; The common explanations include: Sleep typically involves a static position lasting hours at a time with little or no movement. Sleeping on your side places additional pressure on the tendons and bursa of the shoulder. Sleep can cause muscles and tendons to settle in a slightly different position resulting in additional pressure and reduced blood flow. Identifying the underlying problem is important! This allows therapy to focus exclusively on the exact problem or problems. When appropriate conservative care is always the first line of treatment. Focus is typically on strengthening and improving range of motion.
Shoulder pain can be very non-specific, meaning that multiple structures and issues can cause identical pain in the shoulder. Most shoulder examination maneuvers are very limited in their ability to assess exactly what the problem is. With pain when lifting your shoulder, it is critical to take a detailed history, good examination, coupled with imaging to fully understand what is causing the shoulder pain. Many conditions can present with these symptoms
What is the Cause of Shoulder Impingement Syndrome?
Narrowing of the subacromial space is the most common cause of shoulder impingement syndrome (6). The subacromial space is the area between the top of the arm bone (humerus) and the AC joint. This narrowing compresses or pinches the rotator cuff tendons and bursa. If left untreated the rotator cuff tendons can become inflamed, damaged, and or torn.
Causes of Subacromial Space Narrowing
Inflammation or injury of the AC joint
Instability of the AC joint
Increase in the rotator cuff volume due to inflammation or injury.
Can an X-ray Show Shoulder Impingement?
No! X-ray images bone only. Bursa and tendons can not be seen on x-ray. An x-ray may demonstrate arthritis and or a bone spur on the AC joint which can narrow the subacromial space which in turn can potentially compress or pinch the rotator cuff tendons. An MRI is a much better imaging choice as it visualizes bone, ligaments, rotator cuff, and bursa. An MRI can identify shoulder impingement.
Conservative care is the initial treatment of choice if no major damage is present. Options include immobilization, muscular strengthening, physical therapy, ultrasound, acupuncture, and manual therapy.
Steroid injections are often recommended as they are powerful anti-inflammatory agents. These should be avoided as steroids are toxic to orthopedic tissue and may compromise rotator cuff tendon strength and healing. (7)
Surgery is often recommended when conservative treatment fails. The most common surgery for impingement is subacromial decompression where part of the AC joint and bursae are cut away. Unfortunately, the supporting shoulder ligaments are also cut away thereby making the shoulder unstable. New research involving 32 hospitals, 51 surgeons, and more than 300 patients in the United Kingdom demonstrated that decompression surgery is no more effective than a placebo (8).

Platelet Rich Plasma and Stem Cells
PRP is useful in the treatment of shoulder impingement (9). At the Centeno-Schultz Clinic, we have extensive experience in the treatment of shoulder impingement and rotator cuff tears. The instability of the AC joint and shoulder can be treated with ultrasound-guided injections of both PRP and bone marrow concentrate containing stem cells. Mesenchymal stem cells are a type of cell found in your body including bone marrow and fat. They are an all-purpose repairman of the body and these cells have the ability to help tendon injuries heal (10). We published the world’s first research paper on the use of bone marrow concentrate cells on patients with rotator cuff tears with and without arthritis (11). We demonstrated excellent results characterized by a reduction in pain and increase in function after bone marrow concentrate injections.
Shoulder impingement and rotator cuff injuries are among the most common causes of shoulder pain when reaching across the body. Shoulder impingement is a painful condition in which the bursa and muscles of the shoulder are pinched or compressed. This is typically caused by the narrowing of the subacromial space in which shoulder pain when reaching across the body is common. An X-ray may suggest shoulder impingement but MRI is a better imaging choice. Treatment includes conservative care. Steroids should be avoided. Subacromial decompression is a common surgery that is no better than a placebo. PRP and bone marrow concentrate injections are effective, nonsurgical treatment options for shoulder impingement.
