The hardest VA claims to get often involve subjective conditions or proving a strong link (nexus) to service, with PTSD (especially from Military Sexual Trauma - MST), sleep apnea, chronic pain, tinnitus/hearing loss, and claims for aggravation of pre-existing conditions (like flat feet) being notoriously difficult due to lack of objective proof, poor in-service documentation, or proving the worsening went beyond natural progression. Exposure-related illnesses and secondary conditions also present DocHub challenges. Why These Claims Are Hard: PTSD/MST: Requires a verified stressor (hard for MST) and subjective symptoms, often lacking in-service records. Sleep Apnea: Needs a sleep study and proving service connection if not diagnosed in service, often linked to obesity or other issues. Tinnitus Hearing Loss: Common but require specific, calibrated audiograms and functional impact documentation, with tinnitus having a low maximum rating. Chronic Pain/Invisible Injuries: Difficult to objectively measure and often require detailed functional limitation descriptions. Aggravation of Pre-existing Conditions: Requires showing service worsened it beyond normal progression, needing strong before/after evidence and expert opinions. Toxic Exposures (Non-Presumptive): Proving exposure, latency, and nexus without robust scientific evidence is tough. Key Challenges Across Difficult Claims: Lack of In-Service Records: Missing documentation of events or symptoms at the time. Subjective Symptoms: Conditions like pain or mental health struggles are hard to objectively measure. Nexus (Link) Requirement: Proving the military event directly caused or aggravated the condition. How to Improve Your Chances: Gather Extensive Evidence: Buddy statements, personal journals, private medical records, and detailed timelines. Get Expert Opinions: Nexus letters from specialists are crucial. Document Functional Impact: Show how the condition affects your daily life and work. Build a Consistent Record: Show a clear story over time.
