Vertigo and nausea/vomiting anyone?

80-90% clear on symptoms. Out of nowhere today got suddenly dizzy (vertigo…room kinda spinning) and then I threw up twice. Kinda felt clammy and sweaty but no other symptoms. Tiny faint line on one RAT but negative on the other. I get a tiny faint line half the fucking time I take a rapid test and my PCR follow up is always negative. Tinnitus is also the one constant for me that hasn’t recovered. Could this be Ménière's disease? My dad has that. Anyone else experience this? I had vagus nerve issues in march like most long haulers too.
