Undiagnosed Ear Pain. Please help me.

I have pain in both my ears since last two years. There has been no discharge or anything else. But both my ears have continuous pain since last two years. This pain gets accelerated whenever I talk on phone. Both the ears pain equally. It pains at the end of the ear drums and surrounding areas. It even led to survical problem for a month. I was initially treated under doctor K K Handa at Medanta hospital. He gave me pain killers or sleeping pills. Nothing worked. Further I went to AIIMS, they got the CT scan and the MRI but they could not diagnose anything. Was then referred to neurophysician at Apollo. I was treated for depression then but that too dint work. Currently I am under treatment of Dr. Aasis Lahiri at Sir Ganga Ram, when he could not diagnose anything then he too started giving me sleeping pills. Please help me.
