[|Human|] I am 58 years old, female, multiply handicapped and have cardiac, respiratory, and neuro-muscular issues.  I have been treated with nitro-stat, nitro-dur, isorbide for chest pain.  Lately, my blood pressure has been dropping, (I am treated for very high blood pressure) which my physician treats with IV fluids at home.  Today I had a different type of chest pain - not squeezing, and not with very rapid heart rate, it felt like I was being stabbed with a sharp needle over and over again.  I was very weak and slept most of the day.  I am dizzy when I try to get up. Could I be having a heart attack?  Please help.  I cant stay at the computer because I am very dizzy.
[|AI|]  Hifirst rule of medical science is that there is no rule though classical cardiac pain is dull aching squeezing like in nature, yet it can be stabbing needle like pricking sensation also as you have multiple ailments and high blood pressure also it can be a cardiac event a minor myocardial infarction ..... Io would suggest you to go for an ECG and 2d echo test to rule out possibility of a future massive heart attack dizziness, weakness, letharg, lassitude all can be present post myocardial infarction thank you
