Hi I ve been having chest pain on March 17 I went to the ER because I had shortness of breath and chest pain turned out I had pneumonia but I didn t have a cough or any flu like symptoms then I got antibiotics took the pills I was fine they told me to follow up with my doc which I did went in for a physical exam and during that time my antibiotics had finished and I still had chest pain so the doc gave me an Inhailer that actually worked for me back to my blood results they tolde I have H pylori and my ANA blood came back positive can it be because of the infection? I did get antibiotics for the h pylori and they took out more blood too check for lupus what else can cause a positive ANA and last night I felt horrible I had chest pain headache my back was burning i don t know what it can be
