The symptom of earache following flight journey could be due to blockage of the Eustachian tube (the tube connecting nose and the ear) while landing. The swollen ear lobes are not related to the former problem. As of now, treatment is to relieve the earache and the block. Inform your brother to buy xylometazoline
or oxymetazoline nasal spray
or drops (this is a OTC medicine) and use it thrice a day for 3-4days. Also he can buy an anti-inflammatory medicine such as diclofenac
or ibuprofen for the pain relief.
Swollen ear lobes could be due to allergy induced, an antihistaminic such as fexofenadine
or cetrizine will help in relieving the swelling.
