I'm new to this forum, so firstly I would like to say hello to everyone. Secondly, I hope someone can help. And third, this is a bit long, sorry.
My symptoms seemed to start around 7-8 months ago. I would randomly wake up in the middle of the night feeling like I was about to faint/pass out. This happened maybe once a week, but only when I was asleep. About 2 months later it started happening when I was awake as well. I then realised when it happens that my heart started beating heavily, but slowly (about 1 beat every 2 seconds), and I had to lie down for a while. Anyway, I went to the doctors and he checked my heart and said it seemed fine, but if it happened again I was to go straight to the ER. It did happen again and I was admitted and kept in for 3 days. I had blood tests done every day, along with ECG and was attached to a heart monitor. I also had chest x-ray's and ultrasounds done, but all result came back normal. I was discharged and wore a 24hr tape monitor (which I'm still waiting for the results).
During this period, another symptom appeared. I found that I was becoming more breathless when doing day to day activities. It got to the stage that going to brush my teath was to much excersion and I would get lightheaded and breathless. I found that I would randomly get lightheaded when just relaxing, but I would always get lightheaded when I excerted myself. It's been roughly 4 weeks since I last felt lightheaded, until today, but it has only been a slight feeling though. It does however make me feel horrible for a few days.
My doctor said it shows signs that it could be the vagus nerve, but there is nothing much that can be done about it, at least until he see's my 24hr monitor results.
I've done some research and found symptoms that I've had for a couple of years that I have dismissed for one reason or another. These symptoms are some that relate to B12 deficiency, such as randomly numb top right eyelid, loss of proper balance (i.e. I find it really difficult to keep my balance when putting on my socks, etc. which I never used to have). I even notice this when I'm walking that I'm not quite balanced properly. My speech has change as I sometimes get the odd word round the wrong way in a sentence, and I sometimes have difficulty starting a sentence and have to restart it after the first 2 or 3 words. This is really annoying, as I can remember I never used to be like this. Also, I've been getting really tired even though I get 8-9 hours sleep. I've noticed that my short term memory is not as good, as I sometimes take a few minutes to remember what a watched/ate the previous day, etc.
I never mentioned any of the above to my doctor, as my other symptoms appeared more severe and scared me more, so the other symptoms just went out of my head. I have mentioned that I'm getting headaches that last a day or two.
The lightheadedness and breathlessness I think started when I began going to the gym, and rather me getting fitter, I found a was becoming more out of breath when I was away from the gym.
I see my doctor again in just under 2 weeks, and I'll ask about the B12 deficiency, but I would be really grateful if anyone could shed some light on whether it looks more like the vagus nerve or B12 deficiency. I just wish I could get back to feeling normal again.
