Basic self treatment would be Ear de-waxing to eliminate blocking. Then any of the broad spectrum anti biotics. Amoxy etc.

Sometimes the ear wax is accumulated inside the ear, and after taking a hot shower your ear will be blocked.

It's not so easy to clean, don't even try to do do yourself, you can damage the ear drum.

Buy a 3% hydrogen peroxide solution, drop into your ear, keep for 10-15 minutes.

Then wash with water.

Repeat this procedure a few times, but not over 2 times per day.

The 3% hydrogen peroxide solution is pretty safe for the skin.

It is a fairly simple procedure to have a doctor have a look into the ear canal; symptoms you describe are very often associated with blockage of the ear canal.
