hi alice
welcome to healthcaremagic
during an episode of 'cold' or upper
respiratory tract infection, it is quite common to have an eustachian catarrh or Acute
otitis media, which usually resolves without any complications in an adult.
do some steam inhalation and attempt
valsalva manouevere (details are found in various websites).
if these do not give relief pl consult an ENT surgeon
