Just to update all who have responded to my post (thankyou again) I finally managed to get hold of my doc today and have told him I'm not interested in the beta blockers and after much deliberation he agreed to refer me back to cardiology at the hospital, this will take approx 4 weeks!!! I will discuss with an expert what's going on with my heart and hopefully get some answers, I shall of course ask about the aspirin too and will update my post when I've spoken to him/her, it has taken away a little stress knowing I'm going there although I had a set back last night in the way of a huge migraine that woke me from my sleep ( I suffer from classic migraine, the ones with preceding aura) which I haven't had for over a year! I've put this down to stress too, thankyou all for listening through my bad times and I'll hopefully have answers soon
