Lumbar Disc Hernia, Erector Spinae Plane Block, Ilesi

The study is designed as an observational study. Patients who have been treated and completed treatment for lumbar discopathy in our clinic will be followed. Patients will not be divided into groups beforehand, and this will not cause changes to the treatment plan. Patients who have undergone fluoroscopy-guided lumbar interlaminar epidural steroid injection (LESI) and ultrasound-guided lumbar erector spinae plane block (LESP), routinely performed in our clinic for the treatment of back and leg pain due to lumbar disc herniation, will be compared to the effectiveness of these methods on pain at baseline before the procedure and at 2, 6, and 12 weeks afterward using the Visual Analogue Scale for Pain Relief (VAS) and Oswestry Disability Index (ODI). The baseline values will be recorded from the patient files and by request before the start of follow-up.
