I don't know about putting things in your ears, especially if you haven't seen a doctor. Not something I would do.
Definitely keep warm all the time, that always helps. Just make sure you rest as much as possible. Stay hydrated, that makes it easier for your body to recover.
Another thing I can recommend highly is ginger tea (in fact, tea in general is good). You make it by boiling up five or six slices of fresh ginger in hot water for about 10 - 15 mins, and add some lemon or orange pieces if you wish. Then pour & drink.
Hope you get better soon.
