What is a Secondary VA Disability Claim?
A secondary condition is a disability that was caused or aggravated by a service-connected condition. Under 38 CFR § 3.310, the VA will grant service connection for a secondary condition if you can show a medical relationship (nexus) between your already service-connected condition and the new condition.
In this case, you would claim that your service-connected Sciatica caused or worsened your Low Back Pain.
Secondary claims are one of the most effective ways to increase your combined VA disability rating and monthly compensation.

Evidence Needed for This Secondary Claim
1. Nexus Letter (Most Important)
Get a medical opinion letter from a doctor stating that your Low Back Painis "at least as likely as not" caused by or aggravated by your service-connected Sciatica. This is the most critical piece of evidence for a secondary claim.
2. Current Diagnosis
Medical records showing a current diagnosis of Low Back Pain. VA treatment records, private medical records, or a current exam will work.

4. Personal Statement
A detailed statement (VA Form 21-4138) describing how your Sciatica symptoms led to or worsened your Low Back Pain. Include specific examples of how both conditions affect your daily life.
