Thank you for these details.
It might be worthwhile, before attempting to see a doctor, to try a technique to see if the pain might be coming from a pressure imbalance in the ear caused by blockage of the canal that connects the throat and middle ear (the Eustachian tube). To do this, you will need a product sold in pharmacies either Otrivin™ or Dristan™ spray. You simply spray into your nose, wait 30-45 minutes, then pinch your nose, close your mouth and "blow" as if to unclog your ear. However, when blowing, try to swallow at the same time.
It sounds complicated explained like that, but it's not.
If you have a bit of a stuffy nose, it might be worth blowing your nose first or using a product like Hydrasense™.
You can repeat this technique as needed and use Otrivin™ or Dristan™ maximum 3 times a day.
If the technique increases the pain in the ear, or doesn't change anything after 2 days, you'll need to go see a doctor.
Good evening,
