(5) fainting while sitting or standing
(8) edema of airway (larynx, tongue, other)

(6) chest pain
(7) tingling or paresthesias if moderate or marked
(8) any mild reaction that lasts more than 15 minutes
Mild reactions include:

(1) fainting with injury would be classed as severe while fainting without injury would be moderate.
