As i suffered with High Blood pressure problems with Amy, and my BP started to rise the other week, OH went out and bought me a wrist BP monitor (digital one) so icould keep an eye on it myself. But everytime i use it it gives me different readings, i do best of 3 and they are no where near each other!!! I have a cracking headache at the moment and have taken 2 lots of painkillers which haven't shifted it and my head is going muzzy. I don't have swelling and i can't decide whether my blood pressure is raised as it gives me different readings!! Has anyone else used one or knows someone who has?
