question: I had went to the hospital shortly before Christmas because my heart was beating funny. I got diagnosed with P.A.C.. Today I recieved a letter from the hospital notifying me that they had found a 7mm right upper lobe nodule. At the present moment I have no health insurance and am in the process of getting settled in a new state. I guess my question is what should i do now? Im not sure how serious it is and what I need to do.
