If the symptoms are mild and there is evidence of a lesion in the facet joints of the spine or wear and tear of the discs, lifestyle changes, physiotherapy and short-term use of non-steroidal analgesics may be sufficient. However, if a disc protrusion or disc herniation develops, the nerve root or nerve cord exiting the spinal canal is put under pressure. This means that the disc between the vertebrae, which provides the flexibility and pliability of the spine, loses its support and protrudes backwards, possibly tearing the outer fibrous sheath and causing the inner elastic part to come out.
Pressure on the sciatic nerve, known as sciatica, radiates outwards to the nerve supply area and causes sharp pain shooting down the buttocks towards the legs. The pain can vary from mild to excruciating burning, with numbness, pins and needles, loss of sensation, starting mildly and gradually increasing. The pain usually affects one of the lower limbs, following the path of the nerve. In the case of acute, severe spinal pain, it is recommended to spare the spine if possible, and to provide pain relief and reduce inflammation.
In addition to painkillers and anti-inflammatory drugs, the rheumatologist may use muscle relaxant medication, local steroid injections at the site of pain or short infusion treatments called ischial infusions. As the severe pain and inflammation decrease, physical exercise, relaxation and stretching of the affected area, as well as postural exercises and lifestyle changes, will be given priority. If conservative treatment is ineffective, paralysis, faecal dysfunction or urinary retention, surgery may be necessary.
