Hi..I Was Hired As Staff Nurse In Middle East And

Hi..I was hired as staff nurse in Middle East and one of the requirement is to pass medical exam..I've done it last monday and I called the clinic yesterday regarding the result. They ask me to meet the doctor in the clinic because he wants to talk to me regarding my x-ray..accordingly they have seen thickening of the line in my lung,they presumed it is fibrosis and they ask me to go to lung center for the second opinion...My concern now is how am I going to prepare myself before undergoing again the chest x-ray for me to have a normal result..I really need a job abroad..
