In February 2016, it was reported that Kamara had a potential heart condition that could have ended his professional career, leading to his indefinite suspension from playing football. Kamara was evaluated by MLS cardiologist consultant Matthew Martinez, a specialist at MedStar Georgetown University Hospital. After rigorous testing, it was determined that Kamara's condition was not a threat, and he was medically cleared to resume his professional career. He subsequently joined D.C. United in Major League Soccer, with the agreement that he would undergo preventative medical tests at the end of each season.
