'ear 'ear I may be able to help.....it could be a slight middle ear infection. If it is bothering you check it out with your doctor. On no accounts use the over the counter syringes etc.
You should tilt your head to the side so the hurt ear is towards the sky/ceiling. If you are between ages 10-12, put in 5 drops of sweet oil or ear drops. If you are 13-20, put in about 6 drops of sweet oil or ear drops. It worked for me, so it should work for you, too:)!
