I think I suffer from this. My theory: There are muscles in the ear canal that try to modulate the sound and those muscles tense up and cause issues. I also have sore muscles that get a lot better from use of magnesium supplements and the tinnitus also get slightly better from this use. (It get a lot worse if I stop taking it)
how quickly does magnesium work, and how quickly does it get worse if you don't take it?
As of September 9, 2025, hypertension notifications are currently under FDA review and expected to be cleared this month, with availability on Apple Watch Series 9 and later and Apple Watch Ultra 2 and later. The feature is not intended for use by people under 22 years old, those who have been previously diagnosed with hypertension, or pregnant persons.
Sounds a bit ironic but I guess it's for legal reasons.
