Pain along the hypoglossal nerve that may affect the tongue and throat.
Because the rating turns on the degree of lost or impaired motor function of the tongue, medical records that document how much tongue movement you have lost are central. Examination findings that describe tongue strength, coordination, deviation, and range of motion help show whether impairment is moderate or severe. If your involvement is wholly sensory, records showing the nature and extent of sensory symptoms support placement at the mild or moderate level. Speech evaluations or swallowing studies can reflect functional loss tied to tongue motor function. Statements from you or people who know you describing difficulty speaking, eating, or swallowing in daily life can help show how the condition affects function. Records from neurology or otolaryngology visits that track changes over time are also useful for showing the current level of impairment.
