Hello, my sister has sickle cell trait. She is 61 years old and lives in Denver, CO. She was hospitalized last night after her 911 call. Her systems were chest pains, pain in her legs and arms, fatigue, shortness of breath, but no fever. A chest x-ray shows fluid in her lung/lungs. This is the only test result that I have at this time. Her doctors ordered a echo cardiogram and a hematologist will make a visit at some time today. My question to you is it common for someone with sickle cell trait to have a crises like this.
