Internal Medicine

Back pain that radiates down the leg is often a sign of sciatica, a condition caused by irritation or compression of the sciatic nerve. This nerve pain typically stems from a spinal issue such as a herniated disc, spinal stenosis, or bone spurs. Symptoms may include sharp pain, numbness, tingling, or weakness that travels from the lower back through the buttock and down one leg.

Because sciatica can share symptoms with more serious conditions, understanding your specific pattern of pain matters. Take a free, instant, online symptom check to better understand what may be causing your pain and confidently navigate your next steps.

Explanation

When you feel back pain that travels down your leg, it could be a sign of a condition called sciatica. This happens because something is pressing on the nerves in your lower back. The nerves in your back go all the way down your legs, so if they are squeezed or irritated, you might feel pain in your legs.

What Causes Sciatica?

Spinal Issues: Sometimes, problems with the spine like a bulging disc or vertebrae issues can cause sciatica. These problems can press on the nerves, causing pain to shoot down your leg.
Other Factors: Other factors like injury or certain activities might also cause sciatica.

Treatment Options

Medications: Some medications like gabapentin or NSAIDs may help with the pain from sciatica. It's important to talk to a healthcare provider about the best treatment for you.

If you think you might have sciatica, you can check your symptoms to better understand what might be causing your pain and to learn about treatments that might help.
