A few years ago my DH had an attack of Labrynthitis , it came on suddenly , he was so dizzy and omitting , we thought it was a stroke, we called out our Doctor a as my DH couldn't get out of bed , he was diagnosed as having Labrynthitis, he was prescribed , Stemetil and Betahistine, The dizziness went on for months he was so incapacitated, it got so bad we were referred to a consultant who specialised in inner ear problems, He did the Epley manouvres on my DH and showed me how to do them when an attack happened, His last attack happened over four years ago , I did the Epley for him and so far he hasn't had any further trouble, It is a most unpleasant feeling and I sympathise with the OP, it will pass , it just takes time,
One time we were due to fly with the family for a holiday abroad but the day before DH was so poorly we had to cancel our holiday , I would recommend trying the Epley, it moves the chrystals in the inner ear that become displaced by the condition and with time it settles down , that is how the consultant described it to us , I really hope Nams that you get some help with this nd you soon start to feel better , sending flowers and hugs
