Tinnitus help! I sus, allergy/infection.

I am facing tinnitus since a year, i have done all tests, i have got no hearing loss. I got checked with otoscope, the TM looks dull. I have been prescribed steroids, vit b injectns, ginko, multivitamins, even nootropics. Nothing seems to work. I had brain mri, it ws fine. Symptoms i have now is tinnitus is left side 24*7 and after the initial onset of tinnitus on left side, my right is also somehow affected. Also sometimes i get a huge T spike like a whoosh/9k freq tone and that side of head and till middle body feels like collapsing(feeling in nerves usually, bt no sense loss). I also get rashes in body, hives also some unexplained ulcers in arms(attached pics), I have read a T success story who also was having similar symps, and he had been diagnosed with Candidiasis, for which 2 weeks course of nyacin helped. I do have itchy soreness in upper part of ear canal. Can it be fungal? How to diagnose this, please help me! I just want to get to the root of dis and get T free :(. Help me!
