Earwax plug - which can help
It may happen that you wake up in the morning and notice that you hear worse in one ear than on the other. In this case could be an earwax plug.
It helps a simple trick
Fill a hot water bottle with hot water (or heat up grain pillows or moor heat bottle, etc.), place the hot water bottle on a pillow (if necessary lay a spread handkerchief or kitchen paper on top of it) and place the ear again. The heat melts the earwax and drains off. If it does not work right away, repeat.
Otherwise, NEED to see a doctor! In such a case, it could also be a sudden loss of hearing, which must be treated!
