Shoulder pain causes a whole range of problems, affect around 70% of people at some point in their lives.
The shoulder joint is the most mobile joint in the whole body - just think about the movements you can do with your arm compared to your leg.
But it is vital to have good strength and stability to allow all of this shoulder and arm movement without pain and the risk of injury.
Shoulder pain may come on suddenly or build up gradually over time, be linked with a specific injury or have no obvious cause.
Shoulder pain causes may stem from one of the four shoulder joints, the muscles, bones, or other soft tissues such as the labrum. Here we will look at the most common shoulder pain causes, how they develop, typical symptoms and then go on to look at how to treat them.
The most common shoulder pain causes come from:
So let's have a look at the most common shoulder pain causes:
Shoulder impingement syndrome is one of the most common causes of shoulder pain. With impingement syndrome, soft tissues in the shoulder get pinched or trapped leading to inflammation and tearing.
Shoulder impingement is typically caused by anything which reduces the space between the shoulder bones such as bursitis or bone spurs.
Common symptoms of shoulder impingement syndrome are:

Another one of the most common shoulder pain causes is a rotator cuff tear. This is where there is damage to one of the stabilising muscles of the shoulder.
Rotator cuff tears may develop suddenly with an injury such as a fall or heavy lifting, or may develop gradually over time from wear and tear and friction.
Common symptoms of a rotator cuff tear include:

Frozen shoulders, aka adhesive capsulitis, are one of the common shoulder pain causes in women aged 40-60. With a frozen shoulder, there is inflammation, thickening and tightening of the joint capsule.
This may develop following an injury, shoulder surgery or various medical conditions such as diabetes.
Common symptoms include:

Labrum tears, where there is damage to the special layer of cartilage the forms the outer rim of the shoulder socket is another possible cause of shoulder pain.
Labrum tears are usually caused by a sudden injury to the shoulder such as a fall, road traffic accident, awkward/heavy lifting or shoulder dislocation but can also develop gradually with repetitive overhead activities such as decorating.
Common symptoms of a labrum tear include:
Supraspinatus tendonitis is another of the possible shoulder pain causes in middle age. It is caused by irritation and inflammation of the supraspinatus rotator cuff tendon, typically from repeated friction on the tendon caused by narrowing of the subacromial space and/or repetitive overhead activities.
The classic features of supraspinatus tendonitis are:

Biceps tendonitis can cause shoulder pain or elbow pain, depending on which part of the tendon is affected.
Inflammation or degeneration, from repetitive overhead activities, heavy lifting, contact sports or aging leads to inflammation or degeneration of one of the biceps tendons.
Common symptoms of biceps tendonitis include:

Bursitis shoulder pain causes discomfort and restriction of arm movements due to Inflammation of one of the small fluid-filled sacs around the shoulder.
Shoulder bursitis may develop after repetitive overhead activities, a fall, shoulder impingement or certain medical conditions
Common symptoms of shoulder bursitis include:

Snapping scapula syndrome is caused by inflammation of the bursae underneath the shoulder blade aka Subscapularis Bursitis.
It typically develops due to poor posture, overuse, bony abnormality, shoulder weakness or after an injury
Typical shoulder symptoms include:

One of the more serious shoulder pain causes is a fracture or break in one of the shoulder bones.
Shoulder fractures are typically caused by a fall onto the arm or hand, a direct blow to the upper arm/shoulder, or changes in bone structure from aging or osteoporosis.
If you have a broken shoulder, you will normally know about it and there may be:
One of the rarer shoulder pain causes is inflammation of the nerves at the brachial plexus, known as Brachial Neuritis or Parsonage Turner Syndrome.
Brachial neuritis may develop in response to an infection, systemic illness, vaccination, injury or surgery and there may be a genetic predisposition to it.
Typical symptoms of brachial neuritis include:

Another rare cause of shoulder problems is restless arm syndrome. With restless arm syndrome is where there is a problem in the central nervous system which results in abnormal sensations and/or movements in the arms.
You are more prone to developing restless arm syndrome with a dopamine imbalance, pregnancy and certain medical conditions e.g. Parkinson’s & kidney disease and there is a strong genetic link too.
Common symptoms of restless arm syndrome are:

Shoulder acne is a common shoulder problem caused by clogged, irritated skin pores which results in spots or lesions around the shoulder.
Acne at the shoulder or in the arm is usually caused by excess oil secretion, skin friction, excess keratin or an allergic reaction
Different types of shoulder acne present differently and there may be anything from small white or black heads to pus filled spots across the shoulders, arms and back. Shoulder acne may or may not cause shoulder pain
