does caffeine make it worse
Welcome to the forum. Not just caffeine, there are many causes, single or combined, which can trigger or aggravate tinnitus including but not limited to drug reaction or side-effects from ototoxic drugs, ear wax build-up, ear-wax removal suction, inner ear infection, Eustachian tube infection or ETD, ear drum injury, fluid build-up in ears feeling pressured or fullness, sinus infection & congestion especially with a bad cold, TMJ, TTTS, high blood pressure or blood circulation problem, loud noise exposure or acoustic trauma/shock, head trauma & injury, neck injury or muscle problems, hearing loss, Meniere's Decease, barotrauma from sudden change of air pressure such as during landing & taking off on flights especially with blocked nose causing failure to balance the pressure changes, slapping of the ears, deep grief for the loss of loved ones, untreated sleep apnea or lacking enough REM sleep, extreme, extended stress, anxiety & panic disorder, sleep deprivation, etc. T can also be caused or made worse by unhealthy diet such as too much salt, sugar, caffeine (as you mention), MSG, alcohol etc. or by lacking some mineral or vitamin supplements, such as Magnesium, Zinc, B12, D3 etc Some even report that taking away gluten or dairy from their diet reduces T. Tinnitus is just so complicated to figure out sometimes.
