Paralysis of the ilio-inguinal nerve, which may cause numbness in the groin and upper inner thigh.
To support a rating at the 10% level, evidence would need to show severe to complete loss of function of the ilio-inguinal nerve. Medical records documenting the extent of nerve damage, physical examination findings showing the degree of sensory or motor impairment, and nerve conduction or other diagnostic test results can all help establish how severely the nerve is affected. Because this nerve is primarily sensory, records that describe the nature of involvement — sensory only versus mixed — are relevant, since a wholly sensory loss is rated no higher than moderate under the regulation. Statements from you describing how symptoms affect your daily activities and work can support the overall picture of functional loss. If both sides are involved, records documenting bilateral involvement are needed so VA can apply the bilateral factor when combining the ratings.
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.
