Tinnitus query. What should i do.

I have been suffering frm T since a year, i have been prescribed nootropics, renerve injectn, neurokind, antihistamines, decongestants, steroids, everything but nothing seems to work. Only absolut3g or some multivitamin makes a it a little less, my hearing is fine, pta and ia is normal, pta left ear very slight hearing loss. I have bilateral tinnitus, i had brain mri everything is fine, but what i feel is the cause of tinnitus lies in the neck(or possible infected adenoids, as i always get chapped lips, thick mucus in throat), cming to neck, when i workout, when back of my neck(lower back head) got pressed, there was a tinnitus spike, also when i rotate my head, a screeching sound happens as if some nerve is getting pulled tightly and making sound. My dentist told me to get your c1-c3 evaluated, please tell me sir how to go ahead with further diagnosis. What should I do.
