Dolore alla spalla

Shoulder pain causes

See also the separate leaflet called Joint Pain. Shoulder pain is a common problem with a number of different causes which include (starting with the four most common):

Spalla congelata

Spalla congelata is sometimes called adhesive capsulitis of the shoulder. It is a condition where a shoulder becomes painful and stiff. Without treatment, symptoms usually settle but this may take up to 2-3 years.

Rotator cuff disorders

The rotator cuff is a group of muscles and tendons that surround the shoulder joint and help to keep it stable. Rotator cuff disorders are one of the most common causes of shoulder pain. Most people can be successfully treated and have complete recovery.

Pain coming from a problem in the neck.

See the separate leaflets called Neck Pain e Whiplash Neck Sprain.

Acromioclavicular joint disorders

Some conditions (such as a shoulder injury or osteoarthritis) may affect the acromioclavicular joint, which is the joint at the top of the shoulder (see the diagram at the end of this leaflet). Problems with this joint are usually due to wear and tear of the joint or because of injury.

Osteoartrite

Osteoartrite due to general wear and tear in the shoulder joint is a very common cause of shoulder pain.

Artrite settica

Artrite settica is an infection in the joint. Symptoms include pain and tenderness over a joint, pain on moving the joint, and feeling unwell. Septic arthritis is uncommon but needs urgent hospital treatment.

Artrite

Artrite which affects a number of other different joints as well - eg, artrite reumatoide - can cause shoulder pain, but would rarely cause shoulder pain on its own.

Polimialgia reumatica

Polimialgia reumatica is a condition which causes pain, stiffness and tenderness in large muscles, typically around the shoulders, upper arms and hips.

Injury (trauma):

• A broken bone (fracture), such as a fracture of the upper arm bone (humerus) or a broken collarbone (clavicle) can cause shoulder pain.

• Shoulder pain can be caused by a soft tissue injury such as an injury to a ligament, tendon or muscle around the shoulder joint. This may be caused in many different ways, such as a sports injury, a road traffic accident or a shoulder strain following heavy lifting or carrying.

• Shoulder dislocation, where the ball of the joint has moved out of its socket, can cause severe shoulder pain. See the separate leaflet called Joint Dislocations.

Shoulder instability

The shoulder is unstable because the joint does not keep the bones close together. The humerus often 'pops out' of position.

Referred pain

This is a pain which is felt in the shoulder due to the nerve pathways, but is actually caused by a problem elsewhere in the body. The neck is the most common source of referred pain. (See the links above for more information).

Occasionally pain may be felt in the shoulder when the source is the heart or the diaphragm (the muscle which separates the thorax - chest area - from the abdomen - tummy area. A problem within the abdomen can cause an irritation of the diaphragm which can sometimes be felt in the shoulder. Usually in these cases, there is pain in the abdomen or chest as well.

Some general guidelines which may help are as follows. However, remember there are always exceptions to every rule!

• A shoulder pain usually - but not always - comes from a problem with the shoulder. It is more likely to be due to the shoulder itself if it hurts more when moving the shoulder, when touching the shoulder or if the shoulder looks abnormal, for example, if the shape looks different to the other side or if it is hot or red.

• If the shoulder hurts when lifting the arm, it is likely to be due to a problem with the shoulder joint itself, such as a frozen shoulder, rotator cuff problem or shoulder injury.

• If the pain started following a fall or injury of some type, it is likely that the trauma is causing the pain. A bone, joint, ligament, muscle or tendon may be damaged in some way.

• Shoulder pain is very common and can affect all ages. Some causes of shoulder pain, such as osteoarthritis, frozen shoulder and rotator cuff disorders, mainly affect middle-aged and older people. Shoulder pain caused by sports injuries is more common in younger age groups. Sports that more commonly cause shoulder injuries include sports with repeated throwing or bowling, or contact sports such as rugby. Shoulder instability and acromioclavicular joint disorders often affect people who play regular sport.

• If there are pains in other joints as well as the shoulder, it is more likely to be a generalised problem.

• Pain and stiffness in both shoulders which is worse in the mornings or overnight may be due to polimialgia reumatica.

• Clues that suggest shoulder pain is coming from some other problem than the shoulder itself include:

  • If there is a blistery painful or itchy rash, it might be fuoco di Sant'Antonio.

  • If the shoulder pain is coming from the neck, there is likely to be some neck pain and/or stiffness as well.

  • If the pain is in the left shoulder, and if it comes with a pain or tightness in the chest, it may be coming from the heart. Usually with angina or a heart attack, there are other symptoms as well as or instead of shoulder pain. See the separate leaflets called Angina e Attacco di cuore (Infarto miocardico) for details.

  • If many joints are achy and if feeling hot one minute and cold the next, this may be due to a alta temperatura (febbre) due to an infection - for example a raffreddore oppure influenza.

  • If there is tummy pain and pain at the tip of the shoulder blade, it might be coming from the liver or gall bladder in the abdomen.

  • If there is chest pain or shortness of breath or a persisting cough, with pain in the shoulder, it might be due to a problem with the lungs rather than the shoulder.

Generally speaking:

It is sensible to seek medical attention urgently (straightaway) if:

• The pain follows an injury or trauma and is a severe pain or the shoulder cannot be moved at all.

• If the shoulder is hot to touch or red.

• If there is chest pain or difficulty breathing or a feeling of being generally very unwell (call 999/112/911).

Medical attention should be sought soon if:

• The pain is affecting both shoulders and is worse in the mornings or overnight.

• The pain is not improving with simple painkillers for a couple of weeks.

• The pain is affecting your daily activities.

• There are other symptoms as well as shoulder pain, such as:

  • Dolore addominale.

  • A persisting cough.

  • Sudorazioni notturne.

  • Perdita di peso.

  • A blistery rash.

• There is a high temperature (fever) which is not responding to simple measures such as paracetamol, or if there is no obvious simple cause.

• There is a past history of cancer and a persisting pain in the bone area of the shoulder.

• There is new pain in more than one joint.

• There is swelling of the shoulder.

Initial treatment for some of the more common shoulder problems include:

• Taking simple medicines for pain relief, such as ibuprofene oppure paracetamolo.

• Ice packs can also be used to reduce or relieve pain.

• Avoiding activities that may cause more pain in the shoulder, such as heavy lifting and carrying.

If these measures are not working, see a health professional.

This will depend on the cause of the pain.

I trattamenti possono includere:

Fisioterapia

A physiotherapist might advise exercises, perform manipulation and/or recommend a steroid injection into your shoulder.

Rinvio

In some cases, a referral to a bone and joint specialist (orthopaedic specialist or rheumatology specialist) might be advised to see if any further treatment is required, such as a surgical operation to treat the cause of the shoulder pain. Surgery is not needed for most causes of shoulder pain.

Chirurgia

In a few cases an operation may be required. Most commonly, this is done through a 'keyhole' procedure - an arthroscopy. During an arthroscopy, the parts of the shoulder joint can be examined to see what is the cause of the problem. Damaged tissues may be repaired or removed.

Decompression is one surgical option for shoulder tip (subacromial) pain. Decompressing means removing bone spurs and soft tissue through a thin telescope introduced through the keyhole cut. Evidence suggests that there is little value in this particular operation for pain for most people and this should be discussed during the decision-making process.

Occasionally, shoulder joints can be replaced with an artificial joint, particularly if the problem is wear and tear (osteoarthritis).

Medicinali

If the pain is thought to be due to inflammation, such as in artrite reumatoide oppure polimialgia reumatica, then medicines are used. A rheumatologist is needed to prescribe drugs called disease-modifying-drugs for rheumatoid or other inflammatory arthritis. Steroids are usually used for polymyalgia rheumatica and these are usually prescribed in general practice. See the specific leaflets about these conditions for more information about treatment options.

Agopuntura

Recent evidence is that acupuncture may reduce shoulder pain but that more investigation into this is needed.

Investigations might be advised and these will depend on an initial examination to determine the most likely cause of the shoulder pain. Investigations may include:

• Blood tests to look for underlying arthritis such as rheumatoid arthritis.

• X-rays may be needed to diagnose a bone problem or joint problems.

• An ultrasound scan may be needed to assess whether there is a problem with the soft tissues of the shoulder.

• Referral might be needed for further investigations, such as an MRI scan. Specialists include:

  • A doctor specialising in bones and joints (an orthopaedic specialist).

  • A doctor specialising in diagnosis and treatment of arthritis and musculoskeletal conditions (a rheumatology specialist).

  • A physiotherapist.

The outcome will depend on the underlying cause. Shoulder pain may only last for up to a few weeks, may last a few years or may be a lifelong problem. However, if the cause of the shoulder pain is diagnosed and treated early then this can often help to resolve or greatly reduce the pain in the shoulder.

Cuffia dei rotatori

There are three bones in the shoulder region - the collarbone (clavicle), the shoulder blade (scapula) and the upper arm bone (humerus). The scapula is a triangular-shaped bone that has two important parts to it: the acromion and the glenoid. The three bones in the shoulder region form part of two main joints:

• L'articolazione acromioclavicolare tra l'acromion della scapola e la clavicola.

• L'articolazione gleno-omerale tra la glenoide della scapola e l'omero.

There are also a number of muscles, ligaments and tendons around the shoulder. Ligaments are fibres that link bones together at a joint. Tendons are fibres that attach muscle to bone.
