For the past couple of weeks my health has been slowly getting worse. I am fairly healthy usually but recently I've been having headaches, poor memory, poor concentration, dizziness, confusion, blurred vision, heart palpitations and poor balance. It's been very strange!
I went into a supermarket a few days ago and I was squinting the entire way around because my eyes were sensitive to the lights then at one point the room started spinning a little and I grabbed hold of the trolley because I thought DS was rolling away!
I also was walking up the stairs to bed and I was struggling to catch my breath and I went very warm and dizzy.
I've been to the doctors who's going to be giving me a blood test for things such as a vitamin D deficiency and diabetes but I can't remember what else! 
I've had an eye test today to see if that's what was causing it and my vision is perfect. The plot thickens!
I'm curious to see if any of this sounds familiar to anyone? I'm a little worried and wondering if anyone has any idea what these symptoms may suggest.
