Hi there, I've been suffering with what I believe to be RH for just over a year and a few months and just wondered if anyone had any similar experiences and advise? I'm 29 year old male, previously I have been very fit and active with no health concerns, I used the gym regularly, and used to be able to run and play football. The problems all started in December 2017 when I was driving home from work and I started to feel unusual, I had chest pains, and just felt generally unwell. Around the time of this all happening I had 2 bad episodes of suspected Gastritis, I also was drinking lots of red bull and taking pre workout supplements for the gym. I was also under a lot of pressure at work and a close family member had an illness which caused a lot of distress. Since then I have been to the doctors and hospital multiple times, I've had an ECG which was clear, an MRI scan that came back clear, seen an optmothologist, ENT , endocrinologist and numerous blood tests which all where healthy. The endocrinologist diagnosed me as having signs of RH, however he said that I could be hyperventilating? I have had around 25-30 doctor appointments over the last year and a half. They have noted that my liver enzymes may be high (I believe around 66) so I am having further blood tests and an ultra scan to check that. My main symptoms which are pretty much 24/7 on a daily basis: 1. Fuzzy/blurry vision 2. Empty stomach feeling like I need to constantly eat, if I dont eat I start to feel weak, cold, shaky 3. Exhausted from exercise, I used to be able to go to the gym 5 times a week, now if I go I feel very weak after working out and horrendous afterwards, again feeling like I need to eat 4. Brain fog / lack of concentration at work which isn't helped by the blurred vision 5. Tinnitus and ringing in ears 6. Trembly and shaky 7. Chest pain and heart palpitations I have noticed that if I don't eat for a while I start to feel unwell, my hands and feet go extremely cold, I feel heart palpitations, the fuzzy vision worsens and I shake uncontrollably. My symptoms seem to mainly be physical, which is what I believe is causing me some anxiety as well. Its having a serious effect on both my personnel and work life and I'm beginning to feel like I'm at the end of my tether, I am still managing to get to work everyday but it is a struggle, I can no longer enjoy the things I used to do such as using the gym, going out for drinks and socialising with friends and family etc. I've read some extremely helpful articles on the forum, I have since decided to eat a low carb diet to try and help (I'm currently on my 3rd day and I'm really struggling with energy) and I will be going tonight to purchase a blood sugar monitor, I don't know if anyone can recommend any? I've been looking at the accu chek mobile. Appreciate any help/guidance anyone can provide me, thanks a lot.
