T3

The room spins. Your stomach drops. You grab the wall. The shower. The counter. Anything solid because the floor just moved under your feet and nobody warned you. 

ENT said benign positional vertigo. Gave you the Epley maneuver. Sent you home. It came back. Nobody asked about your thyroid. 

Low T3 causes vasoconstriction in the tiny vessels supplying your inner ear. When blood flow drops your vestibular system — your balance center — loses oxygen. The room spins. Not because of displaced crystals. Because of a hormone deficiency restricting blood flow to the most sensitive structures in your body. 

The same mechanism causes the ringing. Tinnitus. Reduced cochlear blood flow creates phantom signals your brain interprets as constant buzzing. The ringing that never stops. That no ENT can fix. Because the cause isn't in your ears. It's in your thyroid. 

Comment THYROID if you've experienced vertigo or tinnitus nobody could explain. Because the spinning might not be an ear problem. It might be a thyroid problem. And ONE organ controlling whether T3 reaches the blood vessels feeding your inner ear.
