All these symptoms suggest that you might be suffering from upper respiratory tract
There is a connecting tract (known as Eustachian tube) between the nasopharynx
& middle ear through which infection can spread to ear.
The management consists of:
1. Drinking of warm fluids to reduce throat pain
2. Antihistamines to provide symptomatic relief from cold
3. Analgesics to take care of headache & fever(if any)
So...it will be better to consult an ENT specialist
for proper physical examination & further management.
Wishing you a speedy recovery.
Thanks & take care.
