Tx ASAP. Systemic reactions to wasp stings can include hives, flushing, swelling of the tongue, mouth , lips & airway; problems breathing, dizziness and in severe cases it can be fatal. Talk with your doctor about carrying self –injectable Epinephrine . You should not delay treatment if you are allergic to wasps.
