It sounds like you may be referring to a Protruded Intervertebral Disc (often called PID or PIVD) causing nerve pain down your leg, or possibly Peripheral Artery Disease (PAD). For temporary relief, generic over-the-counter anti-inflammatory medications like ibuprofen or naproxen can help reduce pain and swelling. If the pain is nerve-related, a doctor may prescribe targeted medications such as gabapentin or muscle relaxants. Because your symptoms severely limit your mobility, please consult a healthcare professional promptly for a proper physical evaluation and an accurate treatment plan. Avoid self-medicating with stronger prescription drugs without a doctor's guidance.
