Yes, I have a problem I m trying to help my brother who is in another country; he went into the er with difficulty breathing, pain in his chest, vomiting and diarrhea. He has Sickle cell anemia. The er didn t treat him immediately and he was admitted later on for treatment of the diarrhea, they said ct found a mass or some kind of cyst on the upper part of his lung; the problem is they don t give a clear diagnosis, I m inquiring for a second guess
