Hi Kay,
I had the same thing about 6 weeks ago. It was horrendous, and seemed to affect my left hand side more than the right, I had dizziness and numbness down one side, couldn't stand up, felt like I was 'tipping' to the left hand side all the time and the wooshing ears. I phoned my GP who diagnosed Labrythitis (not sure if I've spelt that right?!) and prescribed Stemetil, which I took for a few days, but seemed to make the dizziness worse for me, (but I put that down to my body not tolerating any new meds at the moment because it's being stroppy..

)
I don't know if you are on HRT? I started a new HRT regime 4 weeks ago (Mirena Coil and Estrogel) and my symptoms have definitely settled more now, but I have noticed that I still get the 'whooshing' in my ears when I use the Estrogel, which makes me wonder if my previous symptoms were down to hormones after all??
It was a new thing to me, and scared the life out of me (I thought I'd had a TIA, I even went to Urgent Care who assured me I hadn't) I still get the odd dizzy spell but it seems to have settled since the HRT change.
Also, Anxiety can make things like dizziness worse, and suffering from this can bring you down mentally, the symptoms can cause stress and anxiety and it becomes a vicious cycle.
Speak to your GP, they may prescribe something for the dizziness, and think about HRT if you aren't already on it, as it does help with some things.
Take care, and I hope you get some help soon
