Yes, your mother's symptoms are highly consistent with sciatica, which occurs when the sciatic nerve is compressed or irritated. Since the pain affects both legs, it is commonly linked to conditions like spinal stenosis or a herniated disc. This is a very common and manageable condition. For relief, over-the-counter anti-inflammatories like ibuprofen or naproxen can reduce inflammation. For targeted nerve pain, a doctor may prescribe medications such as gabapentin or pregabalin, or muscle relaxants like cyclobenzaprine. Please consult a physician for a proper physical exam to get a personalised treatment plan, which may also include gentle physical therapy.
