My 14 year old has been suffering from headaches, dizziness and occasional chest pain since having a nasty viral infection in February. We’ve had lots of doctors visits and lots of hospital visits through A&E and all they’ve done is blood test (lots of them) which showed nothing. Lots of ECGs which showed Bradycardia which they would expect in a fit boy but he isn’t anymore he went from athletics twice a week, football, cadets and after school activities, in school all day everyday to a child that struggles to manage whole days due to the headaches and dizziness. All we get from doctors is it’s probably just viral and nothing serious but has started to have some times when he has passed out whilst doing activities. I just don’t know what to do the doctors make me feel like I’m stupid and I’m wasting their time but he’s not the happy energetic boy he was and I hate seeing him in pain with his head everyday but making himself go to school even though he’s sent home because he’s to bad by dinner but he says he has to try. He now saying although he’s not well there’s no point going to see doctors because they’re not making him better just taking bloods but 5bats not showing anything. Any help/advice great fully received xx
