One sided pressure of the head and ear popping.

Hello,

Any advice would help...since December I have been suffering from dull headache in the back right side of my head along with a constant ear clicking and popping when i swallow on the right side. It started out as an one sided headache...eventually it turned into back headache with pressure. It happened a day after a plane ride. Been to my Primary DR 3 times now. 1st time he said it could be Occipital nerve pinch...second time in January said that it is still most likely a nerve problem...finally in Feb. they did an MRI...it came back with a non-specific spot that they said was an sinus infection...they started me on antibiotics three weeks worth.I have been on the antibioitcs for one week with little change. Still pressure in the back of my head with ear fullness and clicking...very annoying. I have seen acupuncture, chriopractor. Anybody know any clues on whats going on. I am now going on three months with this problem. I don't really have the classic sinus infection symptons...just dull pressure back of the head one side with ear popping. My eye may twitch now and then. Should I be patient with my antibiotics?
