You are having a real bad attack of upper respiratory infection
and ear ache is because of eustachian tube catarrh. You have to take a good course of antibiotics like augmentin
for 5 to 7 days. Take a pain killer, an antihistaminic and do some warm saline gargles. Though your doctor has told you that you do not have strep infection, but if you are unable to swallow your saliva you must go back to him or an ENT specialist
to rule out quinsy which should be attended to immediately.
