I have chronic sinuitis and that is apart of fms, So if i get to congested in my sinuses then it goes down into ears then i get a lot of fluied in my ears and boom i get vertigo. The one thing i do at home to help myself, is to use
swimmers ear drops in my ears anytime i start having hearing problems, such as ringing , popping, hearing going in and out , or just the sinsation that i might have fluid in my ears , im sure you know all the symstoms.
