[D_AMAZIN]

Im a 29 year old male.my job I work at the airport and I lift heavy luggages ell day.i do currently have anxiety because my job is stressful.do 4 days ago I was feeling chest discomfort.i assume it was my anxiety until I got off work end felt a sharp pain to my chest.the pain would come and go every 5 to 30 mins.i went to kaiser urgent care that night they did en ekg and looked at a x ray I did a few days before that (due to a spasm in leftside of my rib) and the doctor said I just have chest wall pain.i did a follow up immediately the next day with a primary doctor and they told me the same thing and just take asprin and use and heating pad.the next day the pain got worse so I went to a differrnt kaiser did blood work x ray ekg and everything was normal.so today I went to my jobs doctor (an urgent care clinic)they did an ekg and diagnosis me with acute pericarditis.i dont know who to believe because ive been to 4 different doctors and 3 is telling me the same thing but my jobs doctor.

Maybe it would help to read about the symptoms of pericarditis here:

At this point, I would suggest that you make an appointment with a real, honest-to-goodness cardiologist to find out what is actually going on here.
