Im 39,and a mother of three boys.I dont really have any unusual stress and I continued to be told my chest discomfot and irregular heartbeat is anxiety.I get dizzy spells and get very sick to my stomach when this happends.I have had a stress test and a ct my doctor says it is all good.I am in good condition and he always says I have nothing to worry about but I dont feel that way.I get scared when I workout because the irregular heartbeat gets worse.I wonder If I shouldnt see a different doc and see what they say!I hate feeling this way and I also keep it from everyone !
