You should go back and see your doctor again. You should NEVER ignore earache.
I hate to tell you this but using drops/syringing the ear can cause more problems than it solves. (I thought I had a build up of wax and bought the drops and ended up getting an infection!!!) I don't want to worry you, but try to resist putting anything in your ears and do go see him/her again asap.
If you're not happy about what he/she says then keep going back and ask to be refered to an ENT specialist (ear ,nose & throat). This will involve going to the hospital but would be worth it. ENT can refere you for various types of hearing test etc.
Hope that helps, sorry if I worried you.
God bless
