Horrid. I woke up on a Sunday. Had an early night the night before too. Went down stairs to make a cup of tea for us, got back in bed and the room then just started spinning violently. Had it for 3 days solid with vommiting etc.
Had an ambulance come out, which in hindsight was a waste of resource, but at the time I genuinely thought this could be death. A grown man with wife and child around me, I phoned my mum and dad and my mum raced down (collecting a speeding ticket on the way). It really was an experience you never want to go through again.
Tinnitus came a week later. Apparently doesn't come for everyone and 90% of people fully recover from it.
I'm getting there, but not quite. It doesn't thankfully impact my life any more like it did do.
Don't feel bad for calling an ambulance, I did when I had it, or at least the NHS helpline got one for me, or at least a medic on a bike as they were all booked up. Can have similar symptoms to a stroke so they don't mess around. Got me some medication and slept off the worst of it just staying at home.
Labyrinthitis is no joke, Doctors who have had it describe it as one of the most extreme non life threatening things you can get in terms of symptoms. I couldn't walk or barely even move for vomiting, couldn't sleep on my left side for months afterwards for being dizzy. Luckily made a full recovery after a few months with no tinnitus after effects.
