Overview
Brief Summary
The goal of this clinical trial is to demonstrate the efficacy of percutaneous intradiscal radiofrequency as a treatment for radicular pain from lumbar disc herniation.
The main question it aims to answer is:
• Can percutaneous intradiscal radiofrequency lower the severity of radicular pain from lumbar disc herniation Participants will be treated with percutaneous intradiscal radiofrequency and evaluated for radicular pain severity before and 3 months after the procedure.
There is no comparison group.

- •Lumbar disc herniation ≤ 2 locations evidenced by MRI, with ≥ 50% remaining disc height, without disc sequestration
- •Previously treated with epidural steroid injection (ESI) and achieved ≥ 50 % pain relief from local anesthetic effect, confirming radicular pain from lumbar disc herniation, but did not respond to ESI (\< 50 % Pain relief or pain relief \< 3 months)
Exclusion Criteria
- •Patient refusal
- •Previous lumbar spine surgery

Outcomes
Primary Outcomes
Change from baseline radicular pain score at 2 weeks
Time Frame: pre-treatment and 2 week post-treatment
Radicular pain severity using numerical rating scale (0-10) Zero represents 'no pain at all' whereas 10 represents 'the worst pain ever possible'.
Change from baseline radicular pain score at 3 months
Time Frame: pre-treatment and 3 months post-treatment
Radicular pain severity using numerical rating scale (0-10) Zero represents 'no pain at all' whereas 10 represents 'the worst pain ever possible'.
