Overview
Piriformis related leg pain often worsens with sitting climbing stairs or prolonged activity. Symptoms may mimic spinal sciatica but spinal imaging is often normal.
Injection therapy aims to relax the piriformis muscle reduce spasm and relieve pressure on the sciatic nerve allowing improved movement and reduced pain.
Who This Treatment Helps
• Buttock and leg pain worsened by sitting
• Suspected piriformis muscle spasm
• Normal or non explanatory spinal imaging
• Pain not improving with physiotherapy alone
• Restricted hip movement or muscle tightness
What Is a Piriformis Muscle Injection or Botox
A targeted injection of local anaesthetic steroid or Botox is delivered directly into the piriformis muscle using imaging guidance. Botox may be used to provide longer lasting muscle relaxation in selected cases.
What to Expect During the Procedure
Consultant assessment and examination
Comfortable positioning
Image guided injection into the muscle
Short observation period
After the Procedure
It is normal to experience
• Temporary soreness at the injection site
• Gradual reduction in leg pain
• Improved sitting and walking tolerance
Physiotherapy is often recommended to support recovery.
Benefits
• Relieves muscle related nerve compression
• Reduces leg and buttock pain
• Minimally invasive
• Supports rehabilitation and movement
• May prevent unnecessary spinal procedures
Possible Risks and Side Effects
Possible risks include
• Temporary soreness
• Bruising
• Infection rare
• Temporary muscle weakness with Botox
Safety Note
Consultant assessment is essential to confirm diagnosis before treatment.
Arrange a consultation to discuss whether piriformis muscle injection or Botox may be appropriate.
