Hard to say if anything worsens it because tinnitus is prone to variations not only in the sounds heard (hissing, roaring, screeching, rumbling, voices in the distance, uninvited music, thumping) but also in the intensity of the sounds and the combination of different sounds at the same time. They happen spontaneously and what you think might aggravate your tinnitus one day does not the next day. So who knows. I do not find any difference whether I take caffeine, salt, or a small amount of alcohol like a glass of wine. Most high blood pressure can affect tinnitus, particularly loop diuretics. But in most cases if they are listed at all as aggravating tinnitus it is usually considered a « rare » side effect, with the exception of loop diuretics. As to the other part of your question does anything help, I find pregabalin with amitriptyline may help for a few hours. Apart from that I come up with a blank. Just to let you know that I have never tried so called miracle cures. The most helpful thing for me is to listen to nature sounds through my ear buds at a comfortable volume.
