Yes, you can receive VA disability for Functional Neurological Disorder (FND), and your most viable path is to seek service connection on a secondary basis to your already service-connected back and neck conditions, as FND symptoms are often aggravated or precipitated by chronic pain from neurological disorders like radiculopathy and stenosis. The VA rates FND under Diagnostic Code (DC) 9424, "Conversion Disorder," utilizing the General Rating Formula for Mental Disorders found in **38 CFR § 4.130**. Your rating (0%, 10%, 30%, 50%, 70%, or 100%) will be based on the severity of occupational and social impairment, meaning you must thoroughly document how your "constant 8/10 pain" and worsened symptoms—such as functional weakness, seizures, or gait issues—impact your work, self-care, and relationships. Crucially, you need a strong medical nexus linking your FND to your service-connected conditions; your new diagnosis is the starting point, but you must obtain a written opinion from your doctor stating it is "at least as likely as not" that your FND was caused or aggravated by your chronic service-connected pain (**38 CFR § 3.303**). For your increased left-side pain, also consider filing for an increased rating on your radiculopathy under the appropriate peripheral nerve DCs (e.g., DC 8510 for the arm) based on worsened severity, potentially citing *DeLuca v. Brown* regarding functional loss. Your actionable next steps are: 1) File an intent to file immediately to preserve your earliest effective date; 2) Submit a claim for FND as secondary to your back/neck conditions, including all medical records, your FND diagnosis, and a private nexus letter if possible; and 3) Ensure your personal statement details your daily functional limitations since January to support the highest applicable rating under DC 9424.
