Hello dear,
There is a connecting tract (known as Eustachian tube) between the 
nasopharynx & middle ear through which infection can spread to ear.
Also obstruction to this Eustachian tube, secondary to an upper 
respiratory tract infection, 
cold & congestion, can lead to ear pain/fluttering by causing un-equalisation of pressure between the nasopharynx & middle ear.
The management consists of:
1. Drinking of warm fluids.
2. Antihistamines to provide symptomatic relief.
3. Nasal decongestants to relieve ET tube obstruction.
4. Analgesics to take care of pain & fever(if any)
If symptoms still persist, it will be better to consult an 
ENT specialist for proper clinical examination.
Meanwhile, avoid taking cold food & drinks, maintain adequate hydration & take soft, non-spicy foods.
Wish you good health & a speedy recovery.
Take care.
