Hello and thank you for your question. I’d be happy to assist you.
There is nothing to worry.
Just wait and it can drain by itself most likely.
You can do steam inhalation which can help in clearing it.
Also do try Valsalva manoeuvre
-Take a breath in. Then, try to breathe out gently with your mouth closed and pinching your nose. In this way, no air is blown out but you are gently pushing air into the Eustachian tube.
You can use OTC Otrivin nasal spray.
Most likely you'll be fine.
In case you develop muffled hearing,pain,clogged ear then see an ENT specialist for further clinical examination for further evaluation and management.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
Waiting for your response.
It’s my pleasure to continue this conversation until you satisfy.
