This may help:

Have ~10KHz very weak tinitus in left ear, and ~70Hz stronger but still "weak" tinitus in right ear. That combined with feet/legs/hands parasthesia (vibrations mostly, aka mostly no pain). It gets seriously worse during hot summers (reached tinglings and cramps). Ruled "idiopathic" by the docs (MRI scans show nothing "significant") but back and neck seem to be the culprit. Found only one med effective on it, and that only for the first months once the med concentration in the body is "enough": Amitriptyline (dangerous stuff, 2 times I tought it was about to kill me, because it seems my current biology is very sensitive to it). Did stop taking it because of the side effects and worn out effectiveness over time (and like 0 effective during hot summers). Impact, silence is the enemy: Falling asleep happens only when exausted, and intellectual focus is challenging. Usually, I am looking for locations with some some sort of "blank noise". When the parasthesia is too strong, I walk. Basically, only activities which are strong attention attractors are ok. Mindset: Accepted my disability for the rest of my life after years of looking for the causes, and still monitoring any news about it.
