I'm a 20year old male a teatotaller but I drink tea 4 to 6 times a day for last 6 month but now only 1 r 2 a day . I have 135/85 bp in average and 80 to 90 pulse rate 98 oxygen level normal ecg and echo level but I feel having pounding heartbeat chest pains and arm back jaw pain with headache too. I am in fear of having heart attack after recently heart of 35 year old male died of heart attack. My physician said it is lack of calcium and struggled pumping of blood from heart to other parts and it takes 10 to 15 days normal but I have these since last month with some indigestion. Does this indicate heart attack should I seek emergency or else should I take any other tests for confirm heart problems..help me please I am so confused and anxious and I feel a tight head because of this!
