Tinnitus help. Kind of imaging help me?

I have observed one pattern, when I rapidly shake my head my tinnitus sound fluctuates, it seems the sound is of some blood flow. And another thing i marked is when i put pressure towards down to the area shown within the fingers, the tinnitus sound increases as if some nerve is getting compressed and flow of blood is hearable. I highly doubt this is because of any nerve getting compressed, or tmj, as when i open mouth i hear a click sound on my jaw. I have had many medicines for this but it barely helped. It has been there since 4 mnths. Will any kind of imaging help me? No ent doctor till now has prescribed that, I've been past medrol as well. Didn't help much.. Please tell me what should I do. I am afraid of Acoustic Neuroma or any nerve damage.. m really scared and depressed. I lost my social profile as well. Please help me.
