And…The Results Are in

It was results day. I was sitting on a hard plastic chair in the health centre waiting-area, muddling through the Spanish sentences in my head that I wanted to make sure I remembered to say to the specialist. There was an echoey buzz of noise from the conversation of other patients and the rattle of metal trolleys; full of medical folders, being transported to the consultation rooms. I tried to focus on breathing deeply to calm myself. Waiting rooms, the act of waiting, speaking in Spanish about health topics, and the worry of not understanding or hearing the specialist, are all things that make me feel nervous. 

After a short time, I was greeted with a “hello” by a doctor who I immediately recognized from a previous appointment. I smiled and replied “hello”, instantly feeling much of the tension in my body melt away at the realization that we would be communicating in English.

She asked me how I was doing and I told her that I was OK, although I still felt dizzy every day. I explained how I believed that the dizziness was influenced by many things –  crowds of people, tiredness, loud noises, salty foods, changes in weather etc. She said that all these things can cause dizziness, though doctors are not always quite sure of the reasons. Next, she asked me whether I’d had any more vertigo attacks since the last time I had consulted with her, and I answered, telling her I hadn’t.

She then looked at the results of my vestibular tests. “This is good,” she said. She told me that the results showed that my ear was working well to keep me balanced.  I asked her if she meant my right (hearing) ear. She replied with regard to both my ears, saying that my balance system was working to a satisfactory degree. She explained that she was reading some numerical results and that the graphical representations of these results were not currently available – there had been a problem with the printer part of the test-machine when I had taken the test. She said she would need to see the graphs in order to have more understanding of how my vestibular system was functioning. She had a surprisingly positive tone to her voice; something I wasn’t accustomed to hearing in a consultation room.

She conjected that perhaps the diagnoses of endolymphatic hydrops or Meniere’s disease were incorrect, and suggested an alternative reason for my dizziness and unsteadiness being vestibular migraines. I paused for a moment to consider this. I had witnessed my mum experiencing symptoms of traditional migraines for most of her life; something which still continues to affect her almost daily. I wasn’t however, particularly informed about migraine due to inner ear disorders. During these few seconds of contemplation, the specialist had already started to question her new hypothesized diagnosis. She said that although the test results noted a good result, it was probably more likely that I have endolymphatic hydrops or the early stages of Meniere’s disease. She backed this theory up with the evidence that I have pressure in my ear and the fact that consuming salty food also makes me noticeably dizzier and exacerbates the feeling of ear pressure. I had become accustomed to this kind of fluctuation of opinion concerning my diagnosis. Inner ear vestibular disorders are difficult to diagnose, and I was aware that my symptoms could be associated with more than one condition. She said that regardless of the diagnosis, she was happy because the results were good and showed that my brain and ears were working together to keep me balanced.

She then asked me about my experience with vestibular rehabilitation. I told her that I hadn’t noticed a difference in my everyday life, as I still felt dizzy in many situations. She responded unexpectedly by telling me that I had made a lot of improvement during the sessions and that I had almost doubled my test scores, following the treatment. I was happy about this as I had worked hard, and I secretly congratulated myself on my efforts. It seemed that although I was managing my balance more successfully, this didn’t equate to feeling more stable. I was still regularly feeling off-balance and dizzy, yet this was part of my condition. The therapy couldn’t cure these factors, it could only help me manage them more effectively.

I would consult again with the specialist in a couple of months. She reminded me to go immediately to the emergency department of the hospital, should I have any issues, however small, regarding my ears. She also told me to make sure I get plenty of rest, continue to drink lots of water, and keep my salt intake to a minimum. She wrote down the phone number of her receptionists and told me that I could phone them and ask to see her if I ever had any issues with my ears.

I left feeling comforted by the quality of care I had received, and confident that I was doing the best I could to support myself with this condition, whatever it may be.

New Year Tests

It was the first week in January and I was beginning the New Year with a visit to the hospital. Since my vertigo attack, and experiencing increased dizziness during the past few months, I had been referred to a Vestibular Audiologist to carry out some tests. The vestibular system is the inner ear balance mechanism, which works with our eyes and parts of our brain to stop objects blurring when the head moves. I was at the hospital to carry out some Vestibular Function Tests (VFTs) to determine the health of my inner ear balance system; in particular that of my right and only hearing ear. In preparation for the tests, I was told to eat breakfast 3 hours beforehand; to not wear makeup or face cream; and to refrain from consuming caffeine or alcohol for the 48 hours leading up to the tests.

The first test was called a Video Head Impulse Test (vHIT). A friendly-looking woman asked me to sit on a chair facing a wall. On the wall was a silver sticker that was the shape of a paint splodge. She fixed some goggles over my eyes, fiddling with an elasticated strap to make sure they were secured tightly; the plastic pressing into the skin around my eye sockets. She forced my right eye wide-open and trapped it in position with the goggles. She then sat to the left of me at a small desk with a computer. I began to realise that the goggles were making a high pitched noise that I could hear in my right ear. I wondered if they were making the same sound next to my deaf ear; undetected. I figured the glasses had a camera embedded inside them, and that the data would be sent to the computer and then interpreted through some software. I couldn’t look at the screen or what the woman was doing, as she told me to focus my vision on the paint splodge. I sat there for a while whilst I heard her gently tapping the computer keys.

After about 10 minutes she stood up and said something to me in Spanish that I didn’t quite hear nor understand. She held my head in her hands, and started to move it with small sudden motions. During this procedure, I had to continue to keep my focus on the splodge. She carried out this process in 4 short sessions, each one lasting approximately 5 minutes. My hair kept escaping from her grasp and individual strands fell randomly to my face. She kept moving them away and commented on how fine my hair was. After the third session, her phone rang and she had a chat with someone who I gathered, from a few moments of concentrating on her Spanish conversation, were family. It was still Christmastime and the feeling in the hospital was more relaxed than usual. Whilst she was speaking I took the opportunity to look at the computer screen. There was a close-up photo of one of my eyes, and two graphs that were being plotted with what I assume were the reactions of my eyes to each movement. One graph was plotted in a red curve, and the other in blue. I could see, at this moment, that my left side had received a ‘positive’ result and my right side a ‘negative’. I wasn’t sure what this meant, and the test wasn’t over yet. Once the test was finished I felt a little dizzy.

Next was the Caloric Stimulation procedure. I was asked to sit in a chair, similar to one you’d find in a dental clinic. The chair was reclined so that I was lying down and comfortable. Then she fixed another pair of goggles over my eyes. These were bigger than the previous, and pressed forcefully onto the bridge of my nose. The woman explained that the googles had cameras inside to film my eye movements. She then put covers over the lenses so that I lay in darkness. Next, she gently tucked what I assume was a towel, under my chin and around my shoulders. Then, what felt like a small bowl, was placed under my right ear. She informed me that she was going to put some water into my ear and that it was going to sound very loud. She instructed me to keep my eyes open once the water supply stopped. She was going to start by using cold water and would test my right (hearing) ear first. Well, I wasn’t really prepared for what happened next.

I had imagined that a small amount of water would be squirted into my ear; perhaps a syringe-full. First, I heard a mechanical-sounding Spanish voice, coming from a machine – I think it was stating the measurement of water or pressure that had been selected for the test. Then my ear was filled with a high-powered continuous stream of water. It sounded like a storm inside my head. The sensation of the water going in felt cold and as though I was having an intense ear-clean, though it wasn’t too uncomfortable. Once the water stopped flowing, I felt it start to drain out of my ear; trickling into the bowl. I forced my eyes wide open as I had been instructed, and then the dizziness began. The woman had left my side, and I assumed she was now at her computer checking the results. It felt like a mild attack of vertigo. I watched the blackness of the inside of the goggles swirl from one side to the other, and started to feel a little sick. I was aware that the woman was saying something to me, but with some water still in my ear, I was unable to hear her. When all the water had drained, I heard a small satisfying pop and I could hear again. I told her I felt a little sick and dizzy. Once she had the results she needed, she let me rest for a while with my eyes closed. Next, she performed the same routine on my deaf ear. This time the sound of the water entering my ears was silenced; a muffled gurgle. The dizziness following the water spray was slightly more intense, and again I was allowed to rest with my eyes closed, following the taking of results.

I hoped the test was over, but she informed me that she would now repeat the procedure on both ears; this time with hot water. The hot water was a little more uncomfortable than the cold had been, as it entered my ear. As soon as the water began to trickle out, an intense wave of dizziness overtook me. I tried to control my breathing. I started to sweat. I told her I felt really sick. I managed to control the dizziness and nausea, and was allowed to rest a little longer with my eyes closed. I was also instructed to keep my eyes closed as she performed the hot water test in my left (deaf) ear, but to open my eyes wide again once the water stopped. There was some discomfort as it streamed into my ear, accompanied by the subdued sound. I opened my eyes widely once the water pressure had stopped, and I was immediately hit by a surge of strong vertigo. I wanted to close my eyes. I wanted to sit up. I was told to keep my eyes open for a few more seconds whilst the results were being taken. I was sweating more. I became aware of my heart beating wildly in my chest. I focused on controlling my breath; breathing out deeply with my lips puckered tightly into a circle. I held onto the side of the chair to try and keep myself stable.

She rushed over to me and carefully brought the chair back up into a sitting position, and placed what looked like an adult nappy across my forearms and under my chin. She told me to breathe and relax. My stomach cramped as though I was going to vomit, and my head jerked forward. Nothing. I realised why it had been necessary to fast during the three hours before the test. My arms and fingers were tingly and weak; the feeling I used to get as a child from carsickness. I breathed in controlled breaths for some time, as the woman continued to do things at her computer. I started to feel better.

A familiar face appeared in the doorway – it was the specialist who I had consulted with when I first lost my hearing. She recognised me and asked me if I was OK, and she wished me a Happy New Year. The woman made me wait a little while longer after feeling better and then she gave me a sealed envelope, addressed to the ENT department, containing the test results. I would take these with me to my next consultation to discuss with a specialist.  I was then allowed to leave the room and go to my boyfriend who was waiting for me outside.
