Thanks for providing more information.
Sorry for late reply and inconvenience.
Well as you describe possible cause may include Sinus infection and Eustachian tube dysfunction.
And you need to monitor your blood pressure as well.
You should do steam inhalation and saline gargles.
Also take OTC Motrin for pain relief.
Try OTC Sudafed decongestant for short term use.
Use nasal saline spray.
As you have ear drainage so possible there is associated ear infection.
So having said this,you need to be seen by an ENT specialist for a clinical examination for further evaluation and management.
Antibiotics may be prescribed.
I hope this helps.
