Yeah you're right I probably should go back to the doc, I did after the initial "pop" bc my ear was actually hurting and I was scared by how loud the ringing had gotten compared to before, but he did no testing. I've done the hearing test twice in my life & at the time nothing else was wrong besides the tinnitus. & it's funny that you mentioned caffeine, I quit drinking coffee [emoji54] years ago after my gf felt compelled to scare me with that mold study, but I still drink half of a monster energy when I need to, I usually don't drink the whole thing but the other night I had to keep up with my gf doing pickups at ikea & other places for the condo, & I was worried that the ringing was getting louder, even in the crude food court at Potomac mills, but when I woke up next morning it was back to the normal dull ring.
the.earphones i use I think are good enough bc they're small & also acoustic noise canceling, but I try not to put myself where I'm near extremely loud noises lately as it's kind of painful in my right ear.
