Could Taking Allopurinol Cause Chest Heaviness And Dizziness?

Hi There I had a severe gout attack in may 2013, first one ever, never experienced such pain, doctor put me on steroids to clear it which worked, have been on Allipurin ever since only had a very small attack since. I had an heart attack 12 years ago when i was 38 years old, big shock. Have been suffering with dizziness and heaviness in my chest on and off since october, i have been admitted to hospital three times as i thought i was having another heart attack. paid to see consultant to find out what was wrong, they say i have not had another heart attack but are going to give me an angiogram this month to check me out. I wondered if taking Allupurin could have anything to do with the way i am feeling, i just want to feel normal again Any comments would be much appreciated
