i can understand your concern,,dont worry
there is conecting tube called eustuchian tube which conect nose to ear .
as you have infection in upper
respiratory tract including nose throat it may spread to ear through Et tube .when there is blockage of tube with mucus you may have noise feeling in the effected ear
so yawning will releive the blockage simple method of treatment
moreover we require CBP report for blood cell counts and ESR
UNNESSARY TAKING ANTIBIOTIC will cause more harm to body
advisable
x ray PNS to check once infection nose ,
sinuses
if relavant blood report and x ray shows need for antibiotic use according to sensitivity by culture
dont worry it will resolve soon
avoid
cold things and take good diet and healthy life style give good result
