I too have had this for 15 years now! I remember how scary it was early on , especially when your Dc are very small. It took a long time to get an ent referral - had to get a locum to refer me as my GP just kept saying it was "all in my head", een though I had labrythitis - he even refused to prescribe me the SERC the ENT consultant recommended and I had to but it under a private prescrption! GP's are lousy with dizziness - ENT's are too mostly if the results of the bloods and MRI etc are normal.
After the first 4 years I was "discharged" from my the hospital (twice yearly hearing check) as my hearing was not deterirating too badly - I had always been told I had Menieres, but at my last appointment the consultant said he thought I had endolymphatic hydrops (basically Menieres without the hearing loss) but said that there was an outside chance it was perhaps Migraine equivalent (now called migaraine associated dizziness MAV). Most specialists now think most menieres and vertigo is migraine related and can be traced back to childhood motion sickness, head trauma, meningitis, panic attacks, teenage migraine etc.
Last year I was referred back to the hospital as I started to have crippling headaches (on top of the dizziness, spacey feeling, full ears etc) and found the consultant very dismissive - he discharged me as I had "not fallen over" lately. He also said it was probably hormonal as I near my menopause.
Do not despair though - I have met people for whom things have compeletely cleared up who had BPV or residual problems from labs and some for whom Serc or migraine medication has worked.
I found this book helpful www.amazon.co.uk/s/ref=nb_sb_ss_c_1_18?url=search-alias%3Dstripbooks&field-keywords=heal+your+headache&sprefix=heal+your+headache
I am amazed so many people have come on here with their long experiences (only met people on dizzy forums before for whom it seems to clear up) I have felt such a weirdo/outcast over the years - my DP is quite dismissive/tight lipped about it and my family call it "your weird ear thing". My 84 year old MIL recently had a few dizzy turns and was told she may have Menieres - my Dp said but thats what enid has had all these years and she said "no she can't have , its awful - she just has psychosomatic problems!" It is hard because people think you look fine but inside your head you aren't and its tiring.
Does anyonelse have bad problems with the feelings of fullness and pressure in their ears?? all the time - sometimes worse, sometimes better?
OP I hope you start to feel better - cut out caffeine, avoid the sun and flourescent tubes, wear sunglasses and get plenty of rest and water and try the migraine diet (see book rec) and push for another referral or perhaps go private for an inital consultation(i did this while waiting for an appointment and was taken much more seriously and in fact bumped up the queue). Good luck
