###Human: I get excruciating pain while walking due to an injury. Please help. ###Assistant: Hi. I can understand the pain you are suffering from. It is nothing but low back pain radiated to the leg. Due to constant stress and improper posture you get this. Taking rest and doing simple exercises will help reduce pain and also you can take Advil (Ibuprofen) for quick relief. An MRI (magnetic resonance imaging) of LS (lumbar spine) would help to know better what exactly the problem is. Here are some exercises you need to do slowly without any pressure. 1. Low back stretch. 2. Straight leg raising. 3. Piriformis stretch. 4. Bridge. 5. Leg sliding. 5. Waist lifting. 6. Deep abdominal strengthening. These exercises will not only reduce pain but also gives strength to the muscles. Apply heat pad thrice a day. Follow up with MRI reports. Stress, improper posture. MRI lumbar spine. Exercises. Advil tablet. With MRI reports.
