So i have recently found out i have low blood pressure , but recently i have always been cold and shaking and tired and weak a lot. So i tested my blood pressure and it is 85 over 57. I am 14 and i no it should be around 110 over 70. Is this serious or am i just over reacting. And what should i do. Go to doctor asap, call nhs direct, or even call an ambulance. My Family is very worried Please help My mum has a blood pressure testing kit. Yes it is accurate!
