I feel like my ears are blocked and it's as if there is a direct wind blowing in and water inside, but there is nothing like that.

Feeling like your ears are blocked can have various causes. It could be due to a cold, which can cause congestion in the sinuses, or it could be caused by a buildup of earwax. An examination by a healthcare professional can determine if earwax is the issue. If earwax isn't the problem, a technique can help relieve the feeling of blockage by allowing fluid to drain from the ear to the throat. This technique involves using a product like Otrivin to open the canal connecting the ear and throat, followed by a maneuver called Valsalva. If the issue persists for more than 2 days, it's recommended to consult a doctor who may prescribe medication to reduce swelling and promote drainage.
