Understanding sciatica
Sciatica describes symptoms caused by irritation or compression of a nerve root, often producing pain travelling into the buttock or leg. Tingling, altered sensation or weakness may occur.
Making the diagnosis
The pattern of symptoms and neurological examination are important. MRI is sometimes appropriate, especially where symptoms persist or a procedure or surgical opinion is being considered.
Treatment options
Many episodes improve without invasive treatment. Options depend on severity and duration and may include supported activity, appropriate medication, rehabilitation, selected injections or surgical assessment.
When to seek urgent medical attention
Most back and leg pain does not require emergency treatment. However, new difficulty passing urine, loss of bladder or bowel control, numbness around the genitals or back passage (saddle area), or new or rapidly worsening leg weakness may indicate serious nerve compression, including cauda equina syndrome.
Attend an emergency department immediately if these symptoms develop. Do not wait for a routine appointment or email response. New severe back pain with fever or after significant trauma also warrants prompt medical assessment.
