bro its your sinuses. see the pic for reference...

For remedies, i have already suggested what i can. You probably have infection in your sinuses due to flu. So basically go to a doctor, he will take a PNS x-ray. Later he will treat your flu + infection with medicines.
To ease the pain, he will give brufen and may be ear drops (yes it hurts when you put the drops but thats because the pressure built-up inside your sinuses and airways (hence blockage)
On a side not (its not a treatment for your problem but can help)
- Take steam in the morning and before going to bed.
- Take a good quality honey (langnese company ka) in warm water(half glass) twice a day. Its very efficient against flu. The water should be as hot as your tongue/mouth can handle
apart from that my mother used to say ear pain can be treated with: take olive oil, mix some black pepper(NOT crushed). Warm it for some 5 - 10 minutes then put one or two drops in the ear. Wait for 10-15mins then turn your head so that extra oil can flush out. BUT do it at your own risk because i don't know how it will interact with the infection inside.
I however did try the above mentioned remedy and perhaps it worked in the long run. In my case, i had pain in ear, then within an hour i was having pain in cheeks, eyebrows, jaw, later head and neck too. I was awake all night and slept in the morning after taking 2 tablets of panadol to ease it. Thank God when i wokeup pain was all gone, just blockage. Even after that i still took a course of medications.
above all, go see a doctor!
