Sudden swelling beneath the skin or mucous membranes caused by fluid buildup, often affecting the face, throat, or extremities.
Because frequency and laryngeal involvement drive every rating level, the most useful evidence documents each individual attack in detail. Medical records showing emergency room visits, urgent care notes, or calls to your provider during an attack can establish how many attacks occurred within a year and how long each lasted. Records that note whether your throat or airway was affected — such as hoarseness, difficulty swallowing, or stridor — directly support a finding of laryngeal involvement. A treating physician's letter summarizing the pattern of attacks over time, based on clinic visits or telephone encounters, can help fill gaps between formal appointments. Your own written statements, or statements from people who witnessed attacks, can describe the duration, frequency, and symptoms of each episode, including any breathing difficulty that would point to laryngeal involvement. Statements about how attacks have affected your work attendance or daily activities can also give context to the frequency and severity findings in the medical record.
