Lower back pain and sciatica — when should you see a specialist?

Back pain is often caused by overstrain, but pain radiating down the leg, numbness, muscle weakness, or problems with urination require medical evaluation.

Lower back pain is one of the more common reasons patients seek care from a physician, orthopedist, or physical therapist. In many cases, it is related to overuse, prolonged sitting, limited physical activity, injury, or degenerative changes. Back pain itself does not always indicate a serious condition, but its nature, duration, and accompanying symptoms are highly important in determining the next steps.

The most common causes of lower back pain

Lower back pain is most often mechanical — it results from overloading of the muscles, ligaments and joints of the spine. Contributing factors include prolonged sitting, physical work involving lifting, lack of regular exercise, excess weight and weak trunk muscles. With age, degenerative changes in the intervertebral discs and joints become more common; they do not always cause symptoms but may contribute to recurring problems.

An intervertebral disc herniation (spinal disc disease) is a displacement of part of the disc that can compress or irritate a nerve root. It is one of the most common causes of sciatica. In some people, especially older adults, symptoms result from stenosis, i.e. narrowing of the spinal canal — typical features are then leg pain and numbness that increase when walking and ease after resting or bending forward.

Sciatica — symptoms

Sciatica is a common term for pain radiating from the lower back to the buttock and down the leg, often caused by irritation or compression of a nerve root. It may be accompanied by numbness, tingling, a feeling of weakness in the leg, or worsening pain when coughing, sneezing, or sitting for extended periods. Symptoms can vary in severity—from mild to those that significantly limit walking, sleep, and everyday functioning.

Warning signs

Urgent medical attention is required if any red-flag symptoms occur: sudden weakness in the leg, progressively worsening paresis, problems with urination or bowel movements, numbness in the perineal area, fever accompanied by severe back pain, pain after a serious injury, or pain in a person with a history of cancer. In such situations, you should not wait for a routine consultation or rely solely on pain medication.

Diagnosis

The diagnosis of back pain begins with a medical history and physical examination. The doctor or physiotherapist assesses the location of the pain, range of motion, muscle strength, sensation, reflexes, and factors that worsen the symptoms. Imaging tests, such as MRI or X-ray, are not always necessary right away. Whether they are performed depends on the clinical presentation, the duration of symptoms, the presence of neurological signs, and suspicion of a specific cause of the pain.

It is worth knowing that changes visible on MRI, e.g. disc bulges, are also common in people without any symptoms. That is why imaging results are always interpreted together with the patient’s symptoms and examination, not in isolation from them.

Treatment and return to activity

In most patients, acute low back pain and sciatica gradually ease over several weeks. Instead of prolonged bed rest, staying moderately active within the limits of pain tolerance is recommended. When symptoms do not resolve, recur or are accompanied by neurological symptoms, a specialist may suggest options such as physiotherapy, pharmacological treatment, a pain-relief block or — in selected cases — an assessment for surgical treatment.

Treatment is tailored individually. For some patients, the foundation is education, a gradual return to activity, and physiotherapy focused on improving function. In other cases, an orthopedic, neurological, or neurosurgical consultation is needed, especially when symptoms are severe, recurrent, or accompanied by neurological deficits. At ProfessMed, patients with back pain can benefit from specialist consultations and physiotherapy, allowing further treatment to be matched to the true cause of the problem.

Does sciatica go away on its own?

In many patients, sciatica symptoms decrease noticeably within a few weeks, especially when the patient stays active and gradually returns to everyday activities. However, this does not mean you should wait indefinitely. If the pain is very severe, does not decrease or keeps coming back, or if numbness and weakness in the leg appear, a specialist assessment is needed.

How can recurrences be prevented?

The risk of further episodes of pain is reduced by regular physical activity, exercises that strengthen the trunk and gluteal muscles, breaks from prolonged sitting and maintaining a healthy body weight. For office work, adjusting the height of your chair and monitor helps, and for physical work — lifting loads with bent knees and close to the body. A physiotherapist can select a set of exercises for your specific symptoms.

Who should you see?

For back pain without warning signs, an orthopedic or physiotherapy consultation is a good starting point. When pain radiating to the leg, numbness or weakness predominates, a neurological consultation is helpful. A neurosurgeon assesses patients with spinal disc disease, spinal canal stenosis or spondylolisthesis, especially when conservative treatment has not brought improvement or a procedure is being considered.
