Mild discomfort in left ear. Treat this?

For the last 10 days I'm facing a discomfort in my left ear. There is no severe pain while swallowing but there is a constant blunt heaviness and sometimes very mild pain. The area around my adam's apple is also irritated. I have been doing salt water gargle and with Betadine gargle four times a day. It gives me a relief but the discomfort comes back again. I have also taken paracetamol 500 two days but it didn't help much. I don't have fever and my body temperature fluctuates between 97.2- 98.6, but sometimes i feel very warm inside my body as if I have a fever. I feel little fatigued too. There is no cough or runny nose or wheezing but there is a slight itchiness in the throat at times. And I don't feel very good under high speed fans. I am keeping my ear and throat covered. For information, I am taking Acogut 100 for other unassociated reasons. What is going on and how should I treat this?
