hello I'm a 26yr.old female and I have been in the e.r so many times now for chest pains and I have been told so many things 1)i have anxiety.2)to much stress.3)heart palpitations.and the last that scared me was a lung nodule on my right lung so this is why I'm here looking for answers that I did not ask because I was so scared at the time.I had to drink this dye for a ct scan and I had about 2or 3 ct scans and 2 x-rays my doctor tells me that it's nothing to worry about but I do it's only been 3 months since they found the nodule so I was wondering if any one knows if for sure the e.r doctors and my doctor know if it's cancer or not I feel they just teel me this so I won't worry so much because I have three childern the younest is 7 months old.but my pain in my chest is on the right side and it goes through to my back I have been checked for gallstones and everything fine.well the only thing I can think of is my lung because that's where it feels like it's at.so if any one can answer my ?'s can a doctor know for sure if I have lung cancer just by the test's they have done on me? And what test was done when they had me drink that nasty dye and they also put some kind of med.in my I've at the same time I forget what she told me it was but it hurt my vain when she put it in, it kind of made me feel like I was wetting my pants but I was not.if any one can help I would be so grateful and sorry for this being so long but I wanted to make sure I told every thing I can.and again please help me get any answer's
