Just to let you know, I suffered from dizziness two weeks after I had an upper respiratory tract infection which is typical of Labs/VN. I suffered from dizziness and being off balance for a few months before the anxiety kicked in. The dizziness and anxiety subsided after I had been ill for 6 months and I returned to work. I have been to the ENT on a few occassions and though I have never had any MRIs or CAT scans, just the usual hearing tests etc, I was diagnosed first with Labs and then later with VN. I am now left with an off balance feeling, which happens daily but does not last all day. I can now cope with that and live my life pretty normally. However, I cannot work when I catch a cold or virus as it seems to play havoc with my balance. The thing is you can be tested for inner ear disorder and give normal readings even though you do have a problem because they can't actually get to the inner ear, that is what I have heard anyway.
I have also never suffered any deafness but I know that it is my ears that are causing the problems because I do suffer fullness and feel worse when that happens. I am always worse at period time because I retain a lot of fluid and this I believe affects the ears.
I find it interesting that you have trouble swallowing, because I also have the same problem though only when I am trying to fall asleep. I wake up with a jolt, feeling a bit dizzy and I can't swallow which sends me into a panic. I asked my doc about this today and he said that this is normal. Wow, it's great to be so 'normal' isn't it. So bloody frustrating when every test is normal and you just don't know what's wrong!!! I too, often worry that I have something more serious going on inside my head but that is probably because I have not had (and don't want) an MRI etc. You have had all these scans and they have come back normal, so try and be positive and be patient. This inner ear thing has a slow recovery rate so set yourself up for a few knockbacks because that is the way with this illness. Most people who get this problem can recover within 5 weeks, it's just the unlucky ones like us who have to suffer!
You say you have already seen the specialists in this area so I suppose there isn't much more you can do apart from self help, i.e. lots of walking and keeping your head moving.
My balance rehab doctor told me that I wasn't a typical case but my symptoms are exactly the same as lots of people on this board and I have lots of the symptoms listed on the VEDA website. Maybe I am some sort of freak, haha.
Take care and try not to cry too much. Take charge of your life again and beat this monster.
