INTERVENTION: Intervention group: steroid‐hyaluronic‐acid, control group:steroid‐hyaluronidase. CONDITION: lumbar disc herniation and lumbar spinal stenosis. PRIMARY OUTCOME: . Timepoint: . Method of measurement: . Pain and function. Timepoint: Before the intervention, 1 month, 3 months and 6 months after the intervention. Method of measurement: Pain assessment with visual analog scale, function assessment with Roland‐Morris questionnaire and Oswestry Disability Index. INCLUSION CRITERIA: patients aged 20 to 65 years with a BMI <33 with radicular back pain of lumbar disc origin that has not responded to conservative treatments within 6 weeks of treatment. Positive MRI findings of intervertebral disc herniation and canal stenosis or intervertebral foramen stenosis and positive clinical tests in favor of intervertebral disc involvement and lumbar root involvement in EMG/NCS
