Suggest Treatment For Ear Pain

I am a 15 year old male, 5 foot 8, 150 pounds. My medical history includes nose surgery and a few ear infections in my youth. My problem is with my ear. At the beginning of summer 2011, there was a night that I felt excrutiating pain in my head, the biggest headache I have ever had. I had been at the community swimming pool all day, it was my third day there. I woke up the day after that with a loud ringing in my ears and some pain and feeling of fullness. I got it checked out in a week and it turned out to be a minor ear infection. I took amoxcyline for 10 days, but my symptoms did not let up at all. I got my ear checked out again but the doctor said my ear infection was gone, and that it would take a few days for my eustachian tube to drain to ease my symptoms. A month passed with my symptoms only letting up a little bit. I got checked out again in the beginning of september and the doctor diagnosed me with a sinus infection, causing my eustachian tube to swell up, not allowing the fluid to drain from it. He put me on steroid nasal spray for 2 weeks. I did the full treatment, and my symptoms let up just a little bit, but are still there. My full list of symptoms include: Ear ringing, sudden ear pain, jaw pain, pain when chewing occasionally, sharp sudden jaw pain a couple times a week, headaches occasionally, sore throats on some weeks, and thick mucus coming out my nose every few days.
