Clinical and MRI Findings in Lumbar Disc Disease

Low back pain related to lumbar disc disease is a very common condition. Doctors frequently use Magnetic Resonance Imaging (MRI) to look at the spine and diagnose these problems. However, it is not always clear how well the severity of the damage seen on an MRI matches the actual symptoms a patient is experiencing. Sometimes, patients with severe MRI findings have mild symptoms, and vice versa. The purpose of this observational study is to understand the relationship between a patient's clinical symptoms and their MRI results. Researchers want to see if the severity of the spinal damage shown on an MRI can accurately predict how much pain or disability a patient has. Participants in this study are adults (ages 18-70) who are already experiencing symptoms of lumbar disc disease and have recently had an MRI. During the study, participants will: * Complete a questionnaire about the intensity of their back and leg pain. * Fill out a survey about how their back pain affects their daily activities. * Undergo a standard physical and neurological examination by a doctor to check their reflexes, muscle strength, and sensation. Researchers will then compare these physical examination and questionnaire results with the detailed findings from the patient's MRI scans. The goal of this research is to improve diagnostic accuracy and help doctors make better, more personalized treatment decisions for future patients with lower back pain.
