hi and thanks for the query,
during
cold the eustachian tubes get clogged.
these tubes connect the ears to the nose. their fuction is to maintain atmospheric pressure in the ears.
when the tubes get blocked you get blocked sensation in the ears.
follow some simple measures.
1) unclog the tubes with decongestant nose drops like
otrivin. instill 3 drops in each
nostril 3 times a day for 5 days.
2) do not blow your nose forcefully.
3) do not eat cold foods.
4) drink plenty of water.
if you develop pain in your ear or if the symptoms continue for 3 more days then you may need antibiotics.

Dr Rajkishori.
