Constant earache and facial pain..?

I went to the doctor during May, was diagnosed with an ear infection..but a week later the pain was still there so i went back, this time i was seen by a diff doc who checked my nostrils and said they were really inflamed but the ear wasnt infected anymore..so he said i probably have allergies and yr round hayfever (which i already know) as i get all the usual symptoms with it, but my ears have started getting really sore again..they constantly feel blocked and pressurized and sore..any ideas? thanks
