Hi, greetings. Sickle cell anemia in some cases has been demonstrated to be associated with some clinically silent strokes. I would advise you to meet a neurologist for a proper evaluation and probably a good neurologic examination and ct scan. While waiting, its advisable to continue taking your folic acid doses, vaccines against pneumococcus, typhim vi and Hemophilus influennzae. Drink excess water when you feel you are in crises and always have a good pain killer while drinking water with you in case you get crises as you go for your ohysician. For the chest pain, a chest X ray is recommended, although this is a common manifestation during sickle cell crises. Thanks and best regards, Luchuo, MD.
