Thoracic back pain symptoms

Thoracic spine pain is a relatively common symptom but does not tend to persist for long. Often, people will say this type of pain feels as if someone is stabbing them in the back. It is the least common type of back pain but it is more likely than neck pain o low back pain to have a serious cause.

Thoracic back pain red flag symptoms

Thoracic spine pain is usually not sinister and is usually of little consequence. However there are some more concerning features to look out for:

• Recent serious injury, such as a car accident or a fall from a height.

• Minor injury or even just heavy lifting in people who have osteoporosis ('thinning' of the bones).

• Being under 20 years old or over 50 years old when the pain first starts.

• Having a history of cancer, drug misuse, el VIH infection, a condition that suppresses the immune system (immunosuppression) or use of oral steroids for a long time (about six months or more).

• Feeling generally unwell - for example, a temperatura alta (fiebre), chills, sweats, fatigue or unexplained weight loss.

• Having had a recent bacterial infection.

• Pain that is there all the time, which is severe and getting worse.

• Pain at night.

• Pain that wasn't caused by a sprain or strain (non-mechanical).

• Pain that doesn't get better after 2-4 weeks of treatment.

• Pain that is accompanied by severe stiffness in the morning.

• Having changes to the shape of the spine, including the appearance of lumps or bumps.

• Having pins and needles, numbness or weakness of the legs that is severe or gets worse over time.

• Having episodes of incontinence of urine or faeces (this can indicate pressure on the spinal cord).

• Pain that is associated with a cough or feeling short of breath.

The most common cause of thoracic back pain is inflammation. This inflammation can occur for a number of reasons:

• A sudden sprain or strain (as in car accidents or sports injuries).

• Sitting or standing in a slouched position over time (poor posture).

• Using a backpack.

• Sitting for a long time at a computer.

• Lack of muscular strength (which can be improved by regular exercise).

• Repeating a movement persistently that involves the thoracic part of the spine (as in sport or work): also called overuse injury.

Less common causes include:

• Narrowing of part of the spine (thoracic stenosis) - usually due to wear and tear.

• Slipped discs - these are common but do not usually cause pain, however they can do so if they press on one of the nerve roots coming out between the vertebrae.

• Fractures of the vertebrae (the bony components that make up the spine).

• Osteoporosis (this does not cause pain in itself, but can cause a type of fracture of the vertebrae, called a compression fracture, which can cause pain).

• Spinal infection.

• Herpes zóster (especially in people aged over 60 years).

• Spinal artrosis.

• Espondilitis anquilosante - inflammation of the joints between the vertebrae.

• Scheuermann's disease - an inflammation of the joints of the spine which results in spinal curvature.

• Spinal tumours.

It shouldn't be assumed that all pain in the thoracic spine is coming from the spine itself. Other causes of pain in this area can include problems affecting the lung, the uppermost part of the gut (the oesophagus), the stomach, the gallbladder and the pancreas.

Surveys to find out how many people have thoracic spine pain produce very variable results. Evidence from studies suggest that between 15 and 35 in 100 people report having had thoracic back pain at some time. It appears to be as common in children and teenagers as it is in adults and is more common in girls.

Mental health problems seem to be an associated factor as does poor posture. . Adults with thoracic back pain often have aches and pains elsewhere.

Usually there is not a serious cause for thoracic back pain. Most people with thoracic spine pain get better without treatment in a couple of weeks.

However, thoracic back pain is more likely to be due to a serious cause than pain in other areas of the spine (cervical or lumbar spine). There is a whole list of things to look out for that might indicate there's a problem (as listed above).

A short-lived mild pain with an obvious explanation should initially be managed with simple painkillers (such as paracetamol or ibuprofen which can be bought over the counter) and rest / gentle exercise.

However, because thoracic back pain has a higher chance of having a serious cause than neck or lower back pain, a clinician is likely to suggest tests if the pain persists, is severe or is accompanied by any of the 'red flag' features mentioned above.

The tests will depend on the conditions that the clinician wants to assess. They are likely to include blood tests such as a full blood count and inflammatory markers, an x-ray if there is a suspicion of a fracture of one of the vertebrae and maybe a magnetic resonance imaging (MRI) scan.

Most cases will settle without any specific treatment. Simple painkillers and gentle exercise will normally help. If there is an underlying cause, this will need treatment depending on the cause.

Tratamiento médico

If the pain is coming from a joint in the spine (a facet joint) this may be helped by an injection performed under X-ray vision (imaging-guided intra-articular injection).

Surgery which opens the covering of the spinal canal (a procedure called laminectomy) to treat a slipped disc causing thoracic spine pain is occasionally used.

Muscle relaxants used to be suggested for back pain with acute muscle spasm, but there is little evidence for their benefit and they often have side effects and can be addictive, so they are not generally recommended now.

Physiotherapy can be very useful if the pains are not settling.

Self-help treatment

The following can help to reduce and manage thoracic back pain:

• Simple painkillers such as paracetamol or ibuprofen can be bought over the counter. Ibuprofen should be used with care in people over 40 years old or with a history of heartburn or acid reflux.

• Rest can be useful, particularly if someone's normal lifestyle involves heavy lifting or significant exertion. However complete rest is counter-productive as it weakens the muscles around the spine and causes stiffness.

• Gentle exercises such as walking and swimming are beneficial.

• Warm baths or showers can provide relief.

• Correcting poor posture can help.

• Taking breaks from desk based work, and optimising your workstation at work or home can also help.

Thoracic back pain may be caused by an underlying condition. The commonest of these would be a "compression fracture" of a vertebra (where one of the vertebrae gets squashed by the vertebra above it and fractures) which is usually caused by osteoporosis. The best way to prevent osteoporosis is by doing regular weight-bearing exercise (several times a week) and ensuring adequate dietary intake of calcium, as well as not smoking or drinking excess alcohol.

Most commonly, thoracic back pain is simple pain due to muscle strain or inflammation. The best way of preventing this is regular exercise, such as walking or swimming. If the exercise is more vigorous then it is important to do warm up and cool down exercises to reduce the risk of problems. People who do exercises such as weight-lifting should be assessed to ensure they are doing the exercises correctly and safely.

Thoracic back pain can be caused by poor posture, or sitting for long periods, for example, at a desk - avoiding these, and ensuring a desk workstation is ergonomic, can help to prevent it.

Children and adolescents should ensure that they are not wearing backpacks to school which are too heavy. They should also be encouraged to sit with good posture, particularly when using computers or gaming devices.

The outlook (prognosis) depends on the underlying cause, age and general fitness.

Most cases settle down within a few weeks.
