Hi Meryl,

As I have had all the tests in the UK plus my sister and my brother and nothing showed up. I am under an ICC unit (inherited cardiac conditions) and they are very thorough and very senior cardiologists. I was diagnosed around 16 years ago when I had an incident in the gym...downhill all the way. Yes other meds may be at play here as on verapamil, small dose of prednisolone daily 3mgs and Omeprazole every third day. I took it for a week and felt amazing but the headaches started and jaw ache and felt awful. Came off for a week and restarted for three days and they started again. I am very happy for the people it works for of which there are many. Good luck on your journey.
