Hi I ve been having chest pains for about 2 months now it started in the right side then the centre then the left and I had pain in my left arm too which made me panic. I then went to the accident and emergency room and had and ECG doc said there might be a blood clot and so i had a blood test done which were ok doc just said I had high white blood cells. I then visited my GP who said it is probably just muscular pain. The pain remained on my left side for most of the time with some pins and needles on my arm but lately my pain has been excruciating and it is mainly on the centre of my chest and I have really bad pain on my back too directly opposite to the pain on my chest and difficulty taking deep breaths also every now and then I feel a sensation of my heart literally sinking or dropping I don t really know how else to explain it. Gp hasn t been very reassuring (been to them twice now)and they keep saying muscular pain without doing any proper examination like scan etc. What is this pain it is driving me mad and do you think I need any more tests? Also can a blood test and ECG clear you of heart disease and blood clots? By the way I am a 24 year old female. I smoke (trying to quit) and have a lot of spicy food. Thank you for your time.
