If symptoms began in service and continued to today, you can win service connection WITHOUT a formal in-service diagnosis. Build the continuity chain with personal statement + buddy statements + civilian records over time.

The continuity of symptoms doctrine
Key concept. If you can show that symptoms of a condition began in service and have continued without interruption to the present, you can establish service connection even WITHOUT a formal diagnosis in your service records. This is one of the most important tools in the kit for veterans whose conditions weren’t documented during active duty.
38 CFR § 3.303(b) governs this — for chronic diseases listed in § 3.309(a), continuity of symptoms is sufficient.
How to document continuity
- Personal statement (Form 21-4138) describing onset of symptoms in service and continuous experience since.
- Buddy statements from people who knew you during and after service who can attest to symptoms (back pain, limping, anxiety, drinking habits, sleep complaints, etc.).
- Civilian medical records from years after service that document the same symptoms.
- Spouse, family member, or coworker statements describing your symptoms over time.
Strategy
The continuity of symptoms doctrine is most powerful for conditions that historically were under-documented in service: tinnitus (no one filed sick call for ringing in the ears), back pain (“toughed it out”), mental health symptoms (stigma), and chronic skin conditions. Build a continuity chain even if your STRs are silent.
