When my brother was five he had Aplastic anemia and had get Chemotherapy and a bone marrow transplant. He is now 24 and after lower abdomen pains the doctors found out he had fluid around his gallbladder, lungs, and heart. On top of that the sack around his heart is inflamed, Pericarditis. Because of that his heart rate is high and blood pressure low. They drained the fluids. They ruled out many viral infections, bacterial infections, and cancers. It may or may not be connected to his past condition, but they still don’t know. They tried to treat the heart sack with steroids but it looks like they are going to have to do open heart surgery to remove the heart sack. We are looking for another opinion if you have any thoughts?
