ear problem

For the past month or so my ears have been feeling blocked not always but sometimes, and over the last two weeks or so i have been getting a headache everyday. My ears also hurt when i hear a load noise which has to be pretty close to the ear for it to hurt. Also sometimes when im watching tv or at the movies one of my ears felt like pressure went inside of it, i can't really explain it, i didn't lose any hearing or anything but it just felt like my ear went lower? My doctor said its sinus, what do you think?

Get your nose ear and mouth- if you have a bitter taste in mouth looked at, if it is an infection that is causing the sinuses to act up ask if you can get a shot of anti biotics- also if you have allergies the bugs could be affecting that to.
