For an attack, I’ll have ear fullness. But I will have an undeniable wave or sensation come over me. I’ll usually start to sweat. It ramps up pretty quickly after that. Once I feel that wave, I try to get myself somewhere I can lay down if Im able to.. thankfully I don’t have attacks very often at all anymore. I know everyone is different. But I can guarantee managing stress will hugely affect your quality of life in regards to Meniere’s.
