Piriformis Syndrome (Nerve Compression in the Buttock) Treatment Using LLLT/PBMT
Low Level Laser Therapy (LLLT), also known as Photobiomodulation Therapy (PBMT), uses red and near-infrared light applied over targeted areas. In our clinic it is used as part of a GP-led treatment approach for selected musculoskeletal pain and injury presentations, including piriformis syndrome and related gluteal soft tissue presentations.
PBMT/LLLT is non-invasive and generally well tolerated. Suitability and response vary, and treatment recommendations depend on the diagnosis, severity, duration of symptoms and individual clinical factors. PBMT/LLLT has been studied for a range of musculoskeletal pain and injury conditions. See our references page for supporting literature.

Key Points
- Piriformis syndrome occurs when the piriformis muscle in the buttock irritates or compresses the sciatic nerve, causing pain, tingling or numbness along the back of the leg.
- Common contributors include muscle spasm, prolonged sitting, overuse, poor posture or injury to the gluteal region.
- Symptoms typically include buttock pain, radiating leg pain, tingling or numbness and discomfort when sitting for prolonged periods or crossing the legs.
- Standard treatments such as rest, stretching, anti-inflammatory medication or physiotherapy may offer temporary symptom relief for some people, but are not suitable or effective for everyone.
- Low Level Laser Therapy (LLLT), or Photobiomodulation Therapy (PBMT), is considered for selected piriformis syndrome presentations where muscle irritation, local inflammatory processes or nerve sensitivity are contributing to symptoms.
- LLLT may be particularly relevant where pressure, stretching or exercise aggravates sensitive gluteal tissues.
- Treatment is GP-led by Dr Shikha Parmar and delivered under medical supervision as part of a structured six-week program tailored to the patient’s condition.
- LLLT can be considered for people with persistent buttock pain or piriformis-related nerve symptoms who have not improved with usual conservative care, after appropriate medical assessment.
What Is Piriformis Syndrome?
Piriformis syndrome occurs when the piriformis muscle, located in the buttock, irritates or compresses the sciatic nerve that runs from the lower back down the leg.
The piriformis muscle helps rotate the hip and stabilise the pelvis. Muscle spasm, inflammation or tightness can contribute to buttock pain, tingling or numbness along the sciatic nerve distribution.
It may resemble sciatica arising from the spine, but piriformis syndrome originates in the gluteal region rather than from a spinal disc or nerve root.
Causes of Piriformis Syndrome
Several factors may contribute:
- Overuse or prolonged sitting, especially on hard surfaces
- Poor posture or altered body mechanics
- Sudden trauma or injury to the hip or buttock
- Muscle imbalance or tightness involving the piriformis
- Repetitive activities such as running
- Increased pressure on the muscle, including during pregnancy or weight gain
Piriformis syndrome can affect anyone, but is more common in people who sit for prolonged periods or undertake repetitive hip and leg movements.
Symptoms
- Buttock pain, especially when sitting, crossing the legs or rising from a chair
- Radiating pain, tingling or numbness down the back of the leg
- Muscle tightness or spasm in the buttock
- Pain when lying on the affected side or sitting for long periods
- Difficulty walking, running or climbing stairs
- Weakness or reduced flexibility in the hip and buttock area
In more severe cases, symptoms may become persistent and interfere with sleep, mobility and daily activities.
How is Piriformis Syndrome Diagnosed?
Diagnosis is based on a thorough clinical evaluation. Dr Shikha Parmar will take a detailed history of symptoms, activity level and possible contributing factors such as prolonged sitting or recent physical activity. Physical examination assesses tenderness in the buttock and limitations in movement or flexibility.
MRI or ultrasound may be used to exclude other causes of leg pain or assess possible muscle or nerve involvement. X-rays are generally only required where another structural problem is suspected.
Piriformis Syndrome – Treatment Overview
Low Level Laser Therapy (LLLT), also known as Photobiomodulation Therapy (PBMT), is a non-invasive treatment approach used as part of a structured program for selected piriformis syndrome presentations. It may help modulate pain and local inflammatory processes and support muscle and nerve recovery without adding mechanical stress to sensitive gluteal tissues.
Why Consider Low Level Laser Therapy (LLLT)?
Many patients present after limited relief from rest, ice, stretching, anti-inflammatory medication or injections. These approaches may ease symptoms temporarily, but are not suitable for every stage of recovery, especially if pressure, stretching or exercise aggravates sensitive tissues.
Why ice, anti-inflammatories, cortisone, and PRP may not support long-term recovery. Read more here.
How LLLT Supports Healing
LLLT uses red and near-infrared light and may support:
- Helping modulate inflammation and oxidative stress
- Local circulation and oxygenation
- Lymphatic drainage
- Cellular energy production (ATP)
- Muscle and nerve recovery processes where irritation is present
- Assisting pain reduction without mechanical loading or stressing the piriformis muscle
Non-Invasive and Supported by Research
PBMT/LLLT is non-invasive and generally well tolerated. It has been studied in a range of musculoskeletal pain and injury conditions. Individual responses vary, and outcomes depend on the condition being treated and the stage of recovery. Read more here.

Our Treatment Program
All patients are assessed by Dr Shikha Parmar (GP). Treatment is delivered within a structured six-week program, including:
- Up to 12 LLLT sessions
- Early progress review after the first 6 treatments
- Individualised advice and activity modification
- Guided rehabilitation to support longer-term function
Progress is reviewed during the program. Many patients notice appreciable improvement after the first 6 treatments. If there has not been sufficient improvement by this review point, further treatment may not be recommended.
