Sciatica — pain, numbness, or weakness radiating from the lower back through the buttock and down the leg along the sciatic nerve — affects more than a million service-connected veterans. The VA rates it under radiculopathy of the lower extremity, and understanding the rating criteria is essential to getting what you’ve earned.
What “Incomplete Paralysis” Means
You don’t have to be actually paralyzed to receive a sciatica rating. “Incomplete paralysis” in VA terminology means decreased sensation, weakness, pain, or loss of reflexes along the nerve distribution — essentially, any impairment of nerve function that isn’t total. Most veterans with service-connected sciatica receive a 10% or 20% rating depending on whether the examiner characterizes their symptoms as mild or moderate.
Building Your Claim
Service-connecting sciatica requires establishing that it either occurred in service or is secondary to a service-connected condition. The most common path is secondary service connection from a service-connected lumbar spine condition. If your back is already service-connected, your treating physician’s note that the sciatica is caused by or aggravated by the spine condition is usually sufficient nexus.
Bilateral Radiculopathy
If sciatica affects both legs, both sides should be claimed and rated separately. The bilateral factor then applies, increasing your combined rating for both conditions before they’re rolled into your overall combined rating. Many veterans claim one side but not the other — don’t leave the second side unclaimed.
Stacking with Lumbar Spine
Sciatica and lumbar spine (back) conditions are rated separately. A service-connected back at 20% plus service-connected sciatica at 10% (right) and 10% (left) with the bilateral factor can push your combined rating meaningfully higher. These conditions commonly travel together and should all be in your claim.
Can I claim sciatica as a new condition if my back is already service-connected?
Yes — file a claim for increase or new condition secondary to your existing back condition. A nexus letter from your treating physician confirming the relationship is typically sufficient.
What’s the difference between sciatica and radiculopathy in VA claims?
In practical terms, the VA rates both under the peripheral nerve injury schedules. “Sciatica” is the common name; “radiculopathy” is the clinical term the VA typically uses. They refer to the same functional impairment along the sciatic nerve distribution.
