what causes middle back pain and how facet injections help

Middle back pain is one of the most frequently reported  and yet most frequently misunderstood  forms of musculoskeletal discomfort. While lower back pain dominates clinical conversations, pain in the thoracic spine (the middle section of the back, between the base of the neck and the bottom of the ribcage) can be equally debilitating, disrupting posture, sleep, work, and daily mobility.In many cases, the underlying cause of persistent middle back pain is not a muscle problem at all  it is facet joint inflammation. Yet because this condition is frequently overlooked or misdiagnosed, patients can spend months or even years without receiving the targeted treatment that could resolve their pain.

In this guide, Mr Amit  our consultant neurosurgeon at Renew Skin & Health Clinic in Leamington Spa  explains what causes thoracic facet pain, how it is diagnosed, and how facet joint injections can provide effective, lasting relief.

The thoracic spine consists of 12 vertebrae (T1–T12) that run from the base of the neck to the lower back. Unlike the cervical (neck) or lumbar (lower back) regions, the thoracic spine is relatively stable because of its connection to the ribcage. However, this stability does not make it immune to pain and when the small joints that connect the vertebrae become irritated or inflamed, the resulting facet pain can be persistent, difficult to locate precisely, and easily confused with other conditions.

Facet joints  also known as zygapophysial joints  are pairs of small joints located at the back of the spine between each vertebra. They guide and restrict spinal movement, providing stability while allowing controlled rotation and extension. When these joints degenerate or become inflamed, the surrounding nerves are affected, producing the characteristic aching, stiffness, and movement related pain associated with thoracic facet joint inflammation.

There are several recognised causes of facet joint inflammation in the thoracic spine. In many patients, more than one contributing factor is present:

1. Age Related Degeneration
As we age, the cartilage cushioning the facet joints gradually wears down  a process known as spondylosis. This causes the joint surfaces to rub against one another, leading to inflammation, bone spur formation, and progressive pain. Age related degeneration is the most common underlying cause of chronic facet joint pain in adults over 40.

2. Poor Posture and Prolonged Desk Work
Extended periods of sitting  particularly in a forward leaning position at a desk or screen place abnormal compressive forces on the thoracic facet joints. Over time, this sustained load causes micro irritation that can develop into persistent inflammation. This is increasingly common in people who work from home or in office environments, and it is one of the most preventable causes of middle back pain.

3. Previous Spinal Injury or Trauma
A previous injury to the thoracic spine whether from a road traffic accident, a fall, a sports injury, or a workplace incident can alter the mechanics of the spine and place abnormal stress on the facet joints. In some patients, facet joint pain may not develop until months or years after the original injury, making the connection difficult to identify without specialist assessment.

4. Repetitive Strain and Occupational Overuse
Repetitive movements involving twisting, bending, or lifting common in trades, healthcare, retail, and manual labour can cause cumulative wear and irritation of the facet joints. Unlike acute injuries, repetitive strain damage develops gradually and may be dismissed as general back soreness before the underlying facet joint involvement is identified.

5. Arthritis of the Facet Joints
Osteoarthritis  the most common form of arthritis can affect the facet joints directly, causing cartilage loss, joint space narrowing, and bone on bone friction. Inflammatory arthritis conditions, such as ankylosing spondylitis or psoriatic arthritis, may also involve the thoracic facet joints and typically present with additional systemic symptoms that require specialist evaluation.

Diagnosing thoracic facet pain requires a combination of clinical assessment, patient history, and  in many cases  a diagnostic injection procedure. Standard imaging, including X-ray and MRI, may reveal facet joint changes, but imaging findings alone do not always correlate with the level of pain a patient is experiencing.

The most reliable way to confirm the facet joint as the source of pain is through a diagnostic facet joint injection. In this procedure, a small volume of local anaesthetic is injected precisely into or near the target facet joint under ultrasound guidance. If the patient experiences a significant and measurable reduction in pain following the injection, the diagnosis is confirmed.

A medial branch nerve block in which anaesthetic is injected near the nerves that supply the facet joint, rather than into the joint itself  may also be used as a diagnostic tool, particularly when radiofrequency ablation is being considered as a next line treatment.

Facet joint injections are a minimally invasive, evidence based treatment for facet pain treatment that involves delivering a precise combination of anti-inflammatory medication directly into or around the affected thoracic facet joints. The injection typically contains a corticosteroid (to reduce inflammation) and a local anaesthetic (to provide immediate pain relief). Together, these agents work to:

• Reduce the inflammatory process within and around the facet joint
• Block the pain signals transmitted from the joint to the brain via the medial branch nerves
• Improve spinal mobility and posture by removing the muscular guarding response triggered by pain
• Confirm the facet joint as the definitive pain source, guiding future treatment decisions

Mr Amit offers three main types of facet joint injections at our Leamington Spa clinic, each suited to different clinical presentations:

At Renew Skin & Health Clinic, the facet injection procedure is performed as a same day, outpatient treatment. There is no hospital admission and no general anaesthetic. The entire process, from arrival to discharge, is typically completed within two hours.

1. A thorough clinical assessment is carried out by Mr Amit, including a review of your medical history, imaging, and symptom pattern.
2. You are positioned comfortably for the procedure. The skin over the treatment area is cleaned and a local anaesthetic is applied to minimise discomfort.
3. Using real time ultrasound imaging, Mr Amit guides a thin needle with precision to the target thoracic facet joint.
4. The anti inflammatory medication typically a corticosteroid and local anaesthetic combination is injected carefully and accurately into or near the joint.
5. You rest briefly in our clinic for observation before being discharged. Most patients are able to travel home on the same day.

Most patients are able to resume their normal daily activities within 24 hours of the procedure. Mr Amit will provide personalised aftercare instructions at the time of treatment.

The results of facet joint injections vary between patients depending on the severity of joint involvement, the type of injection used, and how long the condition has been present. Based on Mr Amit’s clinical experience and the wider published evidence, patients can typically expect the following:

• Mild soreness at the injection site for 24–48 hours this is a normal response and resolves quickly
• Pain relief that may begin within hours of the procedure, primarily from the local anaesthetic component
• Longer term anti inflammatory relief, from the corticosteroid component, which builds gradually over one to two weeks
• Results that typically last from several weeks to several months, depending on individual response
  The option of repeat injections if the initial treatment is effective and clinically appropriate

For many patients, facet joint injections provide sufficient pain relief to enable active engagement with physiotherapy and rehabilitation  addressing both the symptoms and the underlying movement patterns that may have contributed to the problem in the first place.

At Renew Skin & Health Clinic, we offer two principal types of facet joint injections for middle back pain: corticosteroid injections and hyaluronic acid injections. Choosing the right option depends on the underlying cause of your pain, the degree of joint degeneration, and your overall health profile.

Mr Amit will assess your clinical history, examination findings, and any available imaging to determine which injection type or which combination of approaches is most likely to provide you with sustained facet pain treatment. In some patients, a combination approach is recommended.
