Inflammation or damage to the obturator nerve, which may cause pain or numbness in the inner thigh.
To support a rating of 10%, medical evidence needs to show severe to complete loss of obturator nerve function. Nerve conduction studies or electromyography that document severely reduced or absent nerve signals can reflect this level of impairment. A physician's examination findings showing marked weakness of hip adduction, near-total sensory loss in the inner thigh, or significant gait difficulty tied to obturator nerve damage would also be relevant. If your condition is purely sensory — pain or numbness without motor loss — the regulation places the rating at mild or moderate, meaning evidence of sensory symptoms alone is unlikely to move the rating above 0%. Your own statements describing how pain, weakness, or numbness limits your daily activities or work tasks can help show the severity of functional loss, though those statements work best when they are supported by objective clinical findings in your medical records.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
