DD (12) has been complaining of headaches, and having her vision go spotty for a few seconds and then return straight to normal. She has never actually fainted, but has felt like she is about to multiple times. I think she might just be tired as her sleep schedule since the holidays started is rather questionable, I have advised her to sleep and drink water, but has anyone seen this before, and does anyone have any advice. Anything would be appreciated as I have no idea what is going on and NHS waiting lists are so long, I don’t particularly want to wait in a flu-ridden waiting room if I don’t have to.
